S&S Cycle 84-99 BT Super Stock Cylinder Heads - Wrinkle Natural Aluminum Finish

If you're building a high-performance V-Series engine for your 1984-'99 Harley-Davidson Big Twin, these S&S Cycle Super Stock cylinder heads are a solid choice. They're specifically machined to work with S&S 4-1/8" bore V-Series engines and the 4-1/8" cylinder stud pattern found on S&S Special Application crankcases. These heads are built to feed serious air into your big motor, featuring 2.000" intake valves and 1.605" exhaust valves, all matched with S&S ports designed for ample airflow.

You'll find these heads are ready for S&S electric or manual compression releases, making starting easier on these powerful engines. The manifold mounting surface is machined to stock specifications, meaning you can use stock-height manifolds or throttle bodies without issue, though special length ones might be needed if your engine height isn't stock. The included S&S High Performance valve springs are strong enough to handle camshafts with up to .650" lift, giving you flexibility in tuning your engine's powerband. Plus, they're designed to work with your stock rocker boxes, exhaust, and intake manifolds, simplifying the installation process.

These cylinder heads come with a natural aluminum finish that looks clean and classic. Keep in mind that these are not CARB approved and cannot be shipped to California. For a truly custom build, consider the full range of S&S Cycle performance components.
