S&S Cycle 99-05 BT .585in RW Conical Steel/w/o Compression Release Head Kit - Black

If you're looking to rebuild the top end of your 1999-2005 Big Twin motorcycle, this S&S Cycle .585in RW Conical Steel Head Kit is a solid option. This kit is designed to give your engine a significant performance boost, especially when you're aiming for more power and better airflow through the heads. It's a well-built component that replaces your stock heads with a performance-oriented design.

The .585in RW Conical Steel design means these heads are built for improved airflow and combustion efficiency. The steel construction is strong and durable, meant to handle the increased stresses of a performance engine. This particular kit does not include compression releases, which is common for builds where the camshaft profile and tuning naturally manage starting compression. This means a cleaner look and potentially simpler setup if your starting procedure is already dialed in. S&S Cycle is a well-known name in performance V-twin parts, and this kit reflects their focus on making engines run better.

When installing this kit, remember that it's a major engine component. It's recommended to have a good understanding of engine mechanics or to work with a qualified technician. Ensure you have all the necessary supporting components, such as gaskets, pushrods, and potentially a camshaft that complements the head's performance characteristics. This kit is designed for performance applications and is not CARB approved, so it cannot be shipped to California.
