Description

These S&S Cycle Super Stock® cylinder heads are engineered to work seamlessly with 88" to 103" stock motors, and are an excellent choice for larger stroker or big bore engines up to 110". The large 1.940" intake and 1.575" exhaust valves are designed to maintain optimal port velocity, providing excellent low and midrange response while supplying ample airflow for stock and slightly larger engines to reach their full potential. Featuring S&S® high-performance valve springs, these heads allow for the installation of camshafts with up to .650" lift. The heads can be decked up to 0.060" to increase compression, offering further customization options. Compatible with stock rocker boxes, exhaust, and intake manifolds (unless otherwise noted), and machined for compression releases (sold separately), these cylinder heads offer both immediate performance gains and future upgrade potential. Made in the USA, these 79cc cylinder heads deliver exceptional quality and performance.
