The S&S Cycle Super Stock Cylinder Heads are high-performance, high-flow heads designed for improved engine performance. They feature a port design that enhances airflow while maintaining velocity. These heads are fully assembled with valves and springs, supporting a maximum lift of .640". The 79cc heads have 1.940" intake and 1.575" exhaust valves and are ideal for stock motors ranging from 88" to 103". The 89cc heads feature 2.000" intake and 1.605" exhaust valves, making them best suited for engines over 103" or those with high-compression pop-up pistons. The chamber is designed for stock-style, flat-topped pistons, and the heads are EFI-compatible. They come machined for compression releases (plugs included), but S&S rocker boxes are required if using S&S compression releases. These heads accept OEM intake manifolds and include four long head bolts, reusing four OEM bolts. They are not compatible with Twin Cooled heads and do not include rocker arm components, intake manifold, or gaskets.
