The 799 LS heads are some of the most popular heads used in LS engines. They offer excellent performance and durability and are suitable for many different applications.
These heads were initially designed for the LS7 engine, but they can be used on any LS engine. They are made from cast aluminum and feature large intake and exhaust ports. The 799 heads also have a large combustion chamber, which helps to increase power.
The 799 heads are an excellent choice for many different applications. They offer excellent performance and durability. 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
Before you purchase ported 799 heads, you must know the specifications. This way, you can ensure that the heads will fit your engine and perform as advertised.
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 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-port. Typically, the D-port helps to increase the flow of exhaust gases.
Combustion Chamber Size
The combustion chamber is the space in the cylinder head where the air/fuel mixture is combusted. The size of the chamber can affect power and efficiency.
The 799 LS heads have a large combustion chamber of 64cc. The configuration allows for a higher compression ratio, resulting in more power.
The valves are responsible for letting air and fuel into the cylinder and exhaust out. The size of the valves affects the performance of an engine. The 799 LS heads have 2.00-inch intake valves.
Exhaust Valve Size
The exhaust valve is responsible for venting 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.
Exhaust valve sizes are typically expressed in their diameter, but their area can also specify them. For example, 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.
In an engine, the compression ratio is the ratio between the volume of the cylinder and combustion chamber when the piston is at the bottom dead center (BDC) and the combustion chamber volume when the piston is at the top dead center (TDC). For example, if the volume of the cylinder is 10 liters and that of the combustion chamber is 2 liters, then the compression ratio is 10:2 or 5:1. 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, do 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 when buying ported 799 heads or comparing them with other heads.
The first thing you'll want to consider is the engine displacement. It plays a significant role in selecting suitable heads because it will ultimately determine the airflow potential.
If you have a small displacement engine, you won't need as large ports or valves. But, conversely, if you have a large displacement engine, you'll want larger ports and valves.
Cylinder Head Material
The material of the cylinder heads is also essential to consider. Many ported 799 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 in. For example, if you only drive on the weekends, you can probably get away with a less powerful engine. However, if you're going to be driving in hot weather or at high altitudes, you'll need an engine that can handle harsh conditions.
Finally, you'll want to take the compression ratio into account. It is the ratio of the cylinder volume when the piston is at the top of its stroke to the volume of the cylinder when the piston is at the bottom of its stroke.
A higher compression ratio means less air and fuel in the cylinder, which can lead to increased power. But, it can also lead to engine knock and pre-ignition, so you'll need to be careful.
These are just a few things you'll want to consider when choosing the right cylinder heads. Take your time and compare your options before making a decision. And, if you're still unsure, consult with an expert at MiscAutomotive. We're just a call away.
