Chevy LS1, LS6 Assembled Aluminum Cylinder Head

• 210cc cathedral runners support LS street and performance builds

• 2.000"/1.550" stainless valves improve airflow capacity

• 0.660" lift capability supports aggressive cam profiles

• Fully assembled aluminum construction saves installation time

Upgrade your cathedral-port LS engine with a fully assembled aluminum cylinder head engineered for improved airflow, durability, and performance potential. Featuring 210cc cathedral-style intake runners, 64cc heart-shaped combustion chambers, and 2.000" intake / 1.550" exhaust stainless steel valves, these cylinder heads are designed for performance-oriented LS1, LS6, 4.8L, 5.3L, and 5.7L LS engine combinations.

The 210cc runner design provides an excellent balance of airflow and velocity, helping support strong throttle response, torque production, and horsepower gains across a broad RPM range. Cathedral intake ports and D-port exhaust ports make these heads an excellent choice for naturally aspirated street performance builds, muscle cars, performance trucks, street/strip applications, and LS swap projects.

Constructed from lightweight aluminum, these cylinder heads help reduce weight while dissipating heat more efficiently than comparable iron castings. Stainless steel valves, bronze valve guides, steel valve seats, and chromoly steel retainers provide durability for demanding performance applications, while the assembled design simplifies installation.

With valve spring capability supporting up to 0.660" lift, these assembled LS cylinder heads provide the airflow and valvetrain capacity needed for performance camshaft combinations and serious street performance builds.

Whether you're upgrading an LS1-powered Camaro, an LS6 Corvette, a performance truck, or a custom LS swap project, these assembled aluminum cylinder heads deliver the airflow, durability, and performance enthusiasts demand.
