Chevy Small Block Angled Plug Aluminum Cylinder Head

• 198cc intake runners support street and performance SBC builds

• 2.02"/1.60" valves improve airflow potential

• 64cc heart chambers support efficient combustion

• Bare aluminum casting allows custom valvetrain selection

Build your Small Block Chevy engine with a bare aluminum cylinder head engineered for custom street and performance applications. Featuring 198cc intake runners, 64cc heart-shaped combustion chambers, 2.02" intake valves, 1.60" exhaust valves, and angled spark plug configuration, this cylinder head is designed to support improved airflow and performance across a wide range of Small Block Chevy engine combinations.

The 198cc intake runner design provides an excellent balance of airflow and air velocity, making this cylinder head well suited for 327, 350, 355, 383 stroker, and 400 Small Block Chevy builds. Combined with high-flow intake and exhaust ports, these heads help improve cylinder filling, throttle response, torque production, and horsepower potential throughout the RPM range.

As a bare casting, this cylinder head allows builders to select springs, retainers, seals, and valvetrain components that match their specific camshaft profile and performance goals. This flexibility makes it ideal for custom engine builds, machine shop assembly, street performance vehicles, hot rods, muscle cars, and street/strip applications.

Constructed from lightweight aluminum, this cylinder head helps reduce weight while dissipating heat more efficiently than traditional cast iron heads. Whether you're upgrading a street-driven 350, building a 383 stroker, or assembling a performance Small Block Chevy engine, this bare aluminum cylinder head provides a strong foundation for increased airflow and reliable performance.
