The 799 LS heads are some of the most popular heads used in LS engines. They offer excellent performance with increased horsepower making it a preferred choice for a porting job.
These heads are the latest model and are made using the semi-permanent mold method. While they are similar to 2004 LS2 heads in terms of triangular casting, they do not require cleaning like the 243 heads.

The LS engines designed with 799 heads were 5.3L and 4.8L truck engines. The sophisticated architecture with a cathedral-shaped port allowed it to offer amazing performance on truck engines.

If you are looking for 799 LS heads, Allied Motor Parts is the best place to get them. Call us today.

799 LS Heads Specifications

Ported heads ensure high-quality performance and efficiency. However, before porting, you should make yourself aware of the specifications. For instance, the 799 cylinder heads come with a smaller combustion chamber than its counterparts. So porting to 799 LS heads would mean milling the cylinder heads to cover up for the bigger size of the former combustion chamber.

Material Make

The 799 heads have an aluminum build that can withstand high temperatures. Aluminum is a good material of choice because it is lightweight yet durable.

Intake Port Shape

The intake port forms the final part of the air induction system in an engine. It connects the intake manifold with the cylinder heads.
The 799 LS heads have a cathedral-shaped intake port. The shape is designed to increase airflow and power.

Exhaust Port Shape

The exhaust port in an engine is just as important as the intake. It is responsible for removing the spent gases from the cylinders.
The 799 LS heads have a D-shaped port. Typically, the D-shaped port helps increase the flow of exhaust gases.

Combustion Chamber Size

The combustion chamber is the space in the cylinder where the air/fuel mixture is ignited. The size of the chamber can affect power and efficiency.

The LS heads have a smaller combustion chamber of 64cc. The configuration allows for a higher compression ratio, resulting in more horsepower.

Intake Valve Size

The valves are responsible for letting air and fuel into the cylinder and the exhaust from that combustion out of the cylinders. The size of the valves affects the performance of an engine. The 799 LS heads have 2.00-inch intake valve.

Exhaust Valve Size

The exhaust valve is responsible for expelling the burnt gases off the combustion chamber of an engine after the power stroke. Therefore, the size of the exhaust valve is an essential factor in determining how much power an engine can generate. The exhaust valve should ideally be 85 percent of the size of the intake valve.

The 799 LS heads have a 1.55-inch exhaust valve size.

Intake Port Volume

The intake port volume indicates the total amount of air that the engine can pull into the cylinders during the intake stroke. A larger port volume results in more power, decreasing fuel economy. The intake port volume for 799 LS heads is 209 cc.

Exhaust Port Volume

The exhaust port volume specifies the total amount of exhaust gas that can flow out of the cylinders during the exhaust stroke. The exhaust port volume for 799 LS heads is 74 cc.

Compression

In an internal combustion engine, the compression ratio is the ratio between the volume of the cylinder and combustion chamber at their maximum and minimum values.

In other words, the compression ratio can be defined as the ratio of the volume of the cylinder and its head space when the piston is at the bottom dead center (BDC) and to the volume when the piston is at the top dead center (TDC).

799 cylinder heads have a compression ratio of 9.5:1.

Choosing the Right Cylinder Heads

For many people, selecting suitable cylinder heads can be pretty tricky. For example, should you opt for the Chevy 799 heads, or are the LS 243 cylinder heads better? Are the 799 heads on LS1 interchangeable? If you're uncertain, here are a few factors to consider before going for 799 heads.

Engine Displacement

The first thing you'll want to consider is the engine displacement, also known as cc. The 799 heads cc are smaller compared to its counterparts because of its smaller combustion chamber. It plays a significant role in selecting suitable heads because it will ultimately determine the compression ratio.

While a large combustion chamber reduces the compression ratio, a smaller combustion chamber produces more power due to an increased compression ratio.

Cylinder Head Material

The material of the cylinder heads is another essential feature. Many ported heads are made from aluminum, which is a good choice because it's both solid and lightweight. However, you may also find some heads made from cast iron.

These are usually reserved for larger engines because they can handle the increased displacement and power. But, they are also much heavier than aluminum heads, which can negatively affect performance.
Porting and Polishing

Another factor to consider is whether or not the heads have been ported and polished. Porting and polishing help improve airflow by opening the intake and exhaust ports. You'll want to consider it if you're looking for increased performance.

However, it's important to note that porting is a delicate process. If it's not done correctly, it can decrease performance.

Type of Vehicle

You also need to consider the type of vehicle you have. If you're going to be driving on the street, you won't need as much power as someone who will be racing their car.

You'll also want to consider how often you drive and what kind of conditions you'll be driving. For example, if you only drive on the weekends, you can probably get away with a less powerful engine. However, if you're planning to drive in hot weather or at high altitudes, you'll need an engine that can handle harsh conditions.

Compression Ratio

Finally, you'll want to take the compression ratio into account. A higher compression ratio means more power with less fuel in the cylinder and fewer exhaust gases. But, it also means more heat inside the engine.
Keep the above-mentioned points in mind when choosing the right cylinder heads. Take your time and compare your options before making a decision.

Some people don’t mind their hooded eyes, but it’s understandable if you do. They may feel like just another part of getting older, or your genetics, that you can’t control.

But you can get rid of hooded eyelids. You don’t have to look tired or deal with droopy hooded eyelids anymore. Now there are multiple different treatments that can all drastically change the look of your hooded eyelids.

Which treatments the best, and which ones right for you? This post will give you all the details. But before we do that it’s helpful to know exactly what hooded eyelids are, and how to know if you have them.

What are Hooded Eyelids?

Hooded eyelids are a noticeable amount of skin over the crease of an eyelid. The crease can be partially or fully covered by the skin. This makes the eyelid look smaller, and gives it a “hooded” appearance.

Hooded eyelids are genetic, so they’re natural in some people. They can also develop or become more noticeable as you age.

Hooded eyes aren’t always a bad thing. Even some celebrities have them. But they can cause problems for some people. In some cases hooded eyes can cause discomfort and even make it harder to see.

Other people feel like their hooded eyes negatively affect their appearance, and this is usually the case with hooded eyelids caused by aging.

Not sure if you have hooded eyes or not? It’s pretty easy to tell once you know what to look for.

How to Tell If You Have Hooded Eyes

Eyes generally come in a few different shapes. There are about 5-8 main shapes, depending on who you ask. One of those shapes is hooded eyes.

Sounds complicated right? Luckily it’s pretty easy to tell what shape your eyes are with a few simple questions.

To determine if you have hooded eyes or not, look at yourself in a mirror and ask:

Can I see a full crease above my eyes when my eyes are open?

A full crease will be unobstructed by any skin and continue from one end of your eyelid to the other. If you can’t see a full crease then you either have hooded eyelids or monolid eyes.

Is your eyelid crease covered by skin or do you not have eyelid creases at all?

If your eyelid crease is covered then you have hooded eyelids. Monolids aren’t just covered, they appear to have no crease at all. (monolids are most common in people of East Asian descent)

Hooded eyelids (shown left) shouldn’t be confused with monolids (shown right)

There are different kinds of hooded eyes. They may be deep-set hooded eyes, or possibly a little downturned. If you’re curious about your exact eye shape wikiHow has a great tutorial on how to find it.

But you don’t have to know the exact type of hooded eyes you have if you want to fix them.

How to Get Rid of Hooded Eyelids: The Benefits of Eyelid Tape

The quickest effective treatment for hooded eyelids is eyelid tape. Eyelid tape is a transparent adhesive strip that lifts the skin around your eyelid. This gives your eyes a more open and youthful appearance.

Eyelid tape not only improves the appearance of hooded lids, it can also improve your vision. By lifting excess skin it can clear your field of view.

You might be wondering if eyelid tape is noticeable after you put them on, and how comfortable they are to wear.

The truth is a lot of eyelid tapes brands are poorly made and fall out after just a few hours. That’s why Contours Rx worked to fix these problems with their brand of eyelid tape. So you get all the benefits without the pitfalls of most other brands.

The Benefits of Eyelid Tape
There are a ton of benefits to eyelid tape in general, and even more so for Contours Rx eyelid tape: LIDS BY DESIGN – Eyelid Correcting Strips.

These include:

Instantly improve the appearance of hooded eyelids or tired-looking eyes
Improved vision
They’re long-lasting so you can wear them all day long
No one can see you wearing them, they blend into your skin making them virtually invisible
They’re comfortable to wear

Before and after of Contours Rx’s Eyelid Correcting Strips

The high quality materials are what makes Contours Rx Eyelid Correcting Strips last. The materials were chosen specifically for their hypoallergenic qualities. They’re even dermatologist approved so they’re comfortable to wear.

Best of all they make instant dramatic improvements to the appearance of hooded eyelids. It’s also a great solution to fix hooded eyelids without surgery.

That’s why eyelid strips are the best treatment for most people with hooded eyes. The effectiveness combined with the convenience make them extremely popular.

But there are other solutions to fix hooded eyelids also available.

Other Solutions to Fixing Hooded Eyelids
Makeup and surgery are two other popular treatments for hooded eyelids. These treatments both come with their own benefits, and downsides.

Makeup
Applying makeup in the right places has always been a way to improve your appearance in general, and the same is true for hooded eyelids.

By applying eye shadow in the right places above your eye you can create the illusion of eyelids that look less “hooded.”

Makeup is a popular solution to hooded eyelids. But it’s important to remember it won’t help improve your vision at all. Because the skin above your eyelid isn’t actually being lifted, any obstruction to your vision won’t be removed.

Still makeup can dramatically change the appearance of your hooded eyelids. It does take time to apply – generally much longer than just putting in eyelid strips – but it’s a quick solution compared to surgery.

For people that wouldn’t mind taking the time to skillfully reapply their makeup in specific ways everyday, makeup can fix hooded eyelids.

Surgery
You can fix hooded eyes without surgery, but it’s still an option. The surgery commonly used to fix hooded eyelids is called Blepharoplasty. The surgery is effective, but there are costs and some risks to consider.

First of all is the price. Blepharoplasty, like most surgeries, isn’t cheap. A study performed by the American Society of Plastic Surgeons found the cost of blepharoplasty in 2017 was about $3,026 on average.

In some cases you might be able to get some help paying for it with insurance. That’s because fixing hooded eyelids with blepharoplasty can be a functional surgery to improve your vision. It also depends on what your specific insurance plan covers.

Secondly you should be aware of the risks. All surgeries come with risk. The chances of something going wrong aren’t high if you’re working with an experienced professional. But it’s still important to know the risks involved.

According to Mayo Clinic, a nonprofit medical organization for medical professionals, the risks of blepharoplasty include:

Infection and bleeding
Dry, irritated eyes
Difficulty closing your eyes or other eyelid problems
Noticeable scarring
Injury to eye muscles
Skin discoloration
The need for a follow-up surgery
Temporarily blurred vision or, rarely, loss of eyesight

Lastly you need to consider the time and effort to get the surgery done. After all the work of finding a trustworthy professional you’ll still have to go through a lengthy process of appointments. These include the consultation, followed by multiple appointments before and after the procedure.

Don’t forget the recovery time either. This can be a few weeks, and during that time you’ll have to forego activities you’d normally do during that time. Strenuous labor and wearing contacts are just a few examples of the precautions you have to take while recovering.

After going through all that your hooded eyelids will be fixed. The solution is long-lasting too, so for some this may be worth it.

What is the Best Treatment For Hooded Eyelids?

The treatments for hooded eyelids range from instant effective solutions to costly surgeries that need a lot of preparation. To see what treatment is best for you it’s important to know what your priorities are.

Are you trying to improve the appearance of your hooded eyelids for a special event, or is it to fix your vision? The reasons for fixing your hooded eyelids will be a big factor in deciding what treatment is best for you.

Makeup can be a relatively quick and effective solution. But it takes time and skill to correctly apply the right makeup techniques to improve the appearance of hooded eyelids.

Eyelid tape is another solution that is both quick and effective. It’s easy to put on, lasts all day, and isn’t noticeable. It also has the added benefit of improving your vision, which makeup doesn’t.

Lastly, surgery is another more drastic solution to fixing hooded eyelids. The results of surgery are long-lasting, but you have to weigh out the costs and the risks involved.

Surgery is also a permanent change to your appearance, and that’s a big deal. If you’re interested in surgery, you might want to try eyelid tape first to see the results of what your surgery will look like.

Eyelid tape can lift your eyelids just as well as surgery. So you can use them to see how you’ll look before you make any permanent changes to your appearance.

Contours Rx LIDS BY DESIGN – Eyelid Correcting Strips were made to instantly fix the appearance of hooded eyelids. Whether you want to see what you’d look like after surgery, or you’re just looking for a quick and effective solution, give them a try.

Eyelid Tape – Comparison of Top Eyelid Tape Brands

Eyes come in all shapes and sizes. Apart from eye shape, differences lie in the way the upper eyelid behaves. Some people have smooth eyelids that don’t have much creasing, but most people have excess skin that folds down over the eyelid so much it lays against the lash line. This is known as hooded eyelids, which are a common feature among people regardless of age.

While many starts to see their eyelids become heavier with age, hooded eyelids can also be a genetic trait that has been with them most of their lives. In either case, aging of the skin does tend to produce heavier hooding as the skin becomes thinner over time. Hooded eyelids are not always a cosmetic concern but can also make it difficult to see!

Causes of hooded eyelids



Hooded eyelids are caused by different factors like aging, genetics, or underlying fat and muscle.

Our skin tends to lose elasticity and begins to fall as we age, but the effect is more evident on the face, especially around the eyes. This leads to a noticeable droop around the eyes, appearing hooded.

Besides aging and hereditary traits, other factors that contribute to hooded eyelids include:

Fatty tissue deposits, causing the upper or lower eyelids to appear puffy
Muscle weakness that opens the eye, known as Ptosis
Excess skin around eyes causing wrinkles and bags under the eyes
Why do more people want to treat or lift hooded eyelids?

Women and men are increasingly looking for solutions to hooded eyelids because they feel their hooded eyes make them look tired and aged. Most people have gotten frustrated with makeup applications and have realized they are difficult to hide. Though there are make-up tricks to make the hooded eyes look less hooded, many find it daunting when the mascara or eyeliner leaves a print on the brow bone, or the eyeshadow disappears into folds. In extreme cases, hooded eyelids have fallen so much that some find it difficult to see clearly when driving or reading.

So, how to treat hooded eyelids?

Many surgical, as well as non-surgical treatments, are available to treat hooded eyelids. However, there is an immediate, safe, and effective solution to lift your hooded eyelids with no surgery through the use of eyelid correcting strips.

Eyelid Tape or correcting strips help lift your hooded eyelids by supporting the excess skin up and back into the crease of the eyelid rather than it falling forward.
