About this product
Upgrade your Harley-Davidson's performance with S&S Cycle 89cc Super Stock® Cylinder Heads. These heads are designed to boost power and efficiency, especially in touring bikes and heavier vehicles. Experience improved throttle response and increased horsepower throughout the RPM range.
Description
The S&S Cycle Super Stock® cylinder heads are engineered to maximize airflow and combustion efficiency. Featuring large 2.000" intake and 1.605" exhaust valves, these heads maintain optimal port velocity for excellent low- and mid-range response while providing ample airflow for engines up to 110 cubic inches. The combustion chamber design delivers a slightly higher than stock compression ratio, perfectly suited for larger displacement engines. These heads are compatible with stock rocker boxes, exhaust systems, and intake manifolds, simplifying the upgrade process. Made in the USA, these cylinder heads deliver exceptional quality and performance, ensuring reliability and longevity for your high-performance engine build. With an impressive 264 CFM intake port flow compared to the stock 182 CFM, you will notice a significant improvement in engine breathing and overall power.
