The UMA Racing 22/25 Superhead is a high-performance cylinder head designed to improve engine breathing and unlock more power, especially in modified engine builds. Featuring larger valves (25 mm intake / 22 mm exhaust), it increases airflow through the engine, improving volumetric efficiency, throttle response, and overall performance across the entire RPM range.
Manufactured from high-quality materials with precision-machined components, the UMA Racing Superhead is built to withstand demanding street and racing applications. It is an excellent choice for use with big bore kits, high-performance camshafts, and other performance upgrades.
