Chevy Small Block Straight Plug Aluminum Cylinder Head

Upgrade your Small Block Chevy with bare aluminum cylinder heads engineered to improve airflow, combustion efficiency, and horsepower potential. Featuring 198 cc intake runners, 64 cc combustion chambers, these heads are built for street, strip, and performance engine builds that need better breathing than stock castings.

Improved Airflow & Power Potential
Optimized runner and chamber design helps move more air through the engine, improving throttle response, torque, and top-end horsepower potential across the RPM range.

Performance-Focused Specifications
Key specs such as intake runner volume, combustion chamber size, valve sizing, and straight plug layout are selected to support a strong balance of street drivability and performance output.

Aluminum Construction
Lightweight aluminum construction reduces weight compared to factory iron heads while improving heat dissipation for more consistent performance under demanding conditions.

Built for Street & Performance Builds
Ideal for performance rebuilds, restorations, and upgraded engine combinations. Always verify piston-to-valve clearance, camshaft compatibility, intake manifold fit, and header clearance before final installation.
