S&S Cycle 99-05 BT Super Stock 91cc Cylinder Heads - Silver

If you're looking to get the most out of your late model S&S T124 engine, or a 1999-2005 engine that's been upgraded with the S&S 124" Hot Set Up Kit, these Super Stock cylinder heads are a solid choice. They're built to handle the airflow demands of these larger displacement V-twin powerplants, helping you achieve improved performance.

These heads come with substantial 2.000-inch intake valves and 1.605-inch exhaust valves, paired with S&S's own port designs to ensure a strong flow of air into the combustion chamber. The manifold mounting surface has been specially machined to account for the slightly taller cylinders, meaning you can use a stock-length manifold and throttle body without issue. Inside, high-performance valve springs are installed, rated to handle camshafts with up to .650 inches of lift, giving you flexibility for further engine customization. They are designed to work with your stock rocker boxes, exhaust, and intake manifolds, making the integration into your existing setup more straightforward.

The silver powder coat finish on these heads is a nice touch, designed to match the look of stock silver engine components, helping to maintain a cohesive appearance on your build. While these heads offer significant performance potential, please note they are not CARB approved and cannot be shipped to California.
