799 Heads: All About 799 LS Heads & Their Application

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.
