S&S Super Stock Cylinder Heads For Harley Twin Cam

Enhance your ride's performance with precision-engineered cylinder heads, compatible with both stock flat top and select aftermarket pistons. No need for expert engine-tuning skills—simply install these heads, and experience an immediate boost in power. Although designed to integrate seamlessly with stock parts, pairing them with a high-quality exhaust, air cleaner, and cam will amplify their performance. These heads come equipped with high-lift springs to accommodate more aggressive cam profiles. While not mandatory, adjustable pushrods would complement your engine upgrades. Remember, proper sealing is crucial, so be sure to secure the right gaskets for installation.
