S&s Cycle 79cc Super Stock Cylinder Heads

Upgrade your engine's performance with the S&S Cycle 79cc Super Stock® Cylinder Heads. These heads are meticulously engineered to boost power and efficiency for stock 88" to 103" engines, as well as slightly modified engines up to 110". Experience improved low-end and midrange response, giving you the edge you need on the road.

Description

The S&S Cycle Super Stock® cylinder heads feature moderately sized 1.940" intake and 1.575" exhaust valves, which optimize port velocity for smaller displacement engines, resulting in excellent throttle response and overall performance. Equipped with high-performance valve springs, these heads accommodate camshafts with lifts up to .650". The combustion chamber design yields a significantly higher, yet manageable, compression ratio for increased power output. For those seeking even higher compression, the heads can be decked up to .060", although this will require re-machining of piston valve pockets. These cylinder heads are compatible with stock rocker boxes, exhaust systems, and intake manifolds, simplifying the installation process. Machined to accept S&S® electric or manual compression releases, they offer enhanced control and ease of starting. Proudly made in the USA, these cylinder heads are a testament to S&S Cycle's commitment to quality and performance.
