The Super Stock 79cc and 89cc Cylinder Heads by S&S Cycle are high-performance, high-flow heads designed for enhanced engine power and compatibility with a range of motor sizes. These cylinder heads are fully assembled with valves and springs and are engineered for optimal airflow and velocity. They feature a chamber design tailored for stock-style, flat-topped pistons and are set up to accommodate a maximum lift of 0.640". The 79cc heads are ideal for engines ranging from 88" to 103" and come with 1.940" intake and 1.575" exhaust valves. The 89cc heads are best suited for engines over 103" or those with high-compression pop-up pistons, featuring 2.000" intake and 1.605" exhaust valves. Both options are EFI-compatible and include compression release machining with plugs. These cylinder heads are compatible with OEM intake manifolds and include four long head bolts, with the requirement to reuse four OEM long head bolts. However, they do not include rocker arm components, intake manifolds, or gaskets. If using S&S compression releases, S&S rocker boxes are required. Note that these heads are not compatible with Twin Cooled engines. Designed for durability and peak performance, these heads offer an excellent upgrade path for stock or modified engines.
