Chevy LS1, LS6 Aluminum Cylinder Head
Build your LS engine with a bare aluminum cylinder head designed for custom performance applications. Featuring 210cc cathedral-style intake runners, 64cc heart-shaped combustion chambers, cathedral intake ports, and D-port exhaust ports, this cylinder head is engineered to support increased airflow and performance potential in compatible GM LS engine combinations.
The 210cc intake runner design provides an excellent balance of airflow, throttle response, and velocity, making this cylinder head well suited for naturally aspirated street performance builds, performance trucks, muscle cars, street/strip vehicles, and LS swap projects. The heart-shaped combustion chamber design helps promote efficient combustion while supporting improved torque production and horsepower potential.
As a bare casting, this cylinder head allows engine builders to select valves, springs, retainers, seals, and valvetrain components that match their specific camshaft profile, RPM range, and performance goals. This flexibility makes it ideal for custom engine builds, machine shop assembly, and specialized performance applications.
Constructed from lightweight aluminum, this cylinder head helps reduce weight while dissipating heat more efficiently than cast iron alternatives. Whether you're building a performance 5.3L, 5.7L, 6.0L, or LS swap combination, this bare aluminum cylinder head provides a strong foundation for a custom LS engine build.
Cylinder Head Technology
Designed with 210cc cathedral-style intake runners, 64cc heart-shaped combustion chambers, cathedral intake ports, and D-port exhaust ports, this aluminum cylinder head is engineered to support the airflow requirements of performance-oriented LS engine combinations. The bare casting configuration allows builders to select valvetrain components that match their specific performance goals.
Performance Benefits
The 210cc runner design helps maintain strong air velocity while supporting increased airflow, making this cylinder head suitable for a wide range of street and performance applications. Aluminum construction helps reduce weight and dissipate heat efficiently, supporting improved throttle response, torque production, and horsepower potential.
