Cylinder Heads - 79 cc - Super Stock® - Twin Cam

Enhance your Twin Cam engine with the S&S CYCLE 79 cc Super Stock® Cylinder Heads (Part Number: 900-0251). These heads come fully assembled with springs and valves, providing a straightforward upgrade that improves performance across low and midrange RPMs. Designed to work seamlessly with stock motors from 88" to 103", they are also ideal for larger stroker or big bore engines up to 110", ensuring your bike maintains optimal airflow and responsiveness. The large 1.940" intake and 1.575" exhaust valves help sustain port velocity, which translates into better throttle response and power delivery. Made in the USA, these heads are machined for high performance and durability, with features that support a wide range of modifications for increased output.

The heads feature S&S® high-performance valve springs capable of accommodating camshafts with up to .650" lift, unless otherwise noted. This flexibility allows enthusiasts to upgrade their cams for even more power. Additionally, the heads can be decked up to 0.060" to increase compression, further enhancing engine efficiency and performance. Compatibility with stock rocker boxes, exhaust, and intake manifolds simplifies installation, enabling a hassle-free upgrade process. Please note that the heads are machined for compression releases, which are sold separately, and piston valve pockets may require re-machining if higher lift cams or decking are used.

These cylinder heads deliver high port flow, ensuring excellent performance now and room for future upgrades. They do not include rocker arm components, intake manifold, or gaskets, and should not be used with pistons that have a pop-up dome. For heads equipped with S&S compression releases, compatible S&S rocker boxes are required. Overall, the S&S CYCLE 79 cc Super Stock® Heads are an excellent choice for riders seeking reliable, high-performance engine components that maximize power and efficiency, all crafted with precision in the USA.
