Questions About LS/LT Cylinder Heads

What should I consider when choosing cylinder heads for my LS or LT engine?

Consider the intended use of your vehicle (street, track, or racing), the desired power level, and compatibility with your engine configuration. Our range includes options for various applications, ensuring you find the right heads for your build.

What is the benefit of using as-cast cylinder heads?

As-cast heads are typically more affordable and offer improved airflow compared to stock heads. They are a great option for enthusiasts looking to upgrade without the added cost of full CNC porting.

How do CNC-ported cylinder heads improve engine performance?

CNC-ported heads enhance airflow and combustion efficiency, leading to significant gains in horsepower, torque, and overall engine responsiveness. The precise porting process ensures optimal flow characteristics for maximum performance.

How does cylinder head porting affect fuel efficiency?

By improving airflow and combustion efficiency, ported cylinder heads can enhance fuel efficiency. The engine breathes better, burns fuel more completely, and operates more efficiently, leading to potential fuel savings.
