Description

Upgrade your Ford Small Block Windsor with bare aluminum cylinder heads engineered to improve airflow, combustion efficiency, and horsepower potential. Featuring 185cc intake runners, 60cc 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.

Bare Head Build Flexibility
Bare cylinder head configuration gives builders the flexibility to select valves, springs, retainers, and hardware matched to the exact camshaft, RPM range, and power goal.

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.
