S&S Cycle 84-99 BT Performance Replacement Low Compression 82cc Cylinder Heads - Natural

If you're looking to rebuild or upgrade the top end of your 1986-1999 Harley-Davidson Evolution Big Twin engine, these S&S Cycle Performance Replacement cylinder heads are a solid option. They are designed to work with stock-style flat-topped pistons and feature an 82cc combustion chamber, which helps manage compression ratios for larger displacement builds. These heads are even original equipment on S&S V96 and V80 engines, so you know they're built for performance.

You'll notice larger than stock valves here: 1.900 inches for the intake and 1.575 inches for the exhaust. This setup allows for plenty of airflow while keeping port velocity up, which is key for good low and midrange response. The included high-lift valve springs can handle cams with up to .585 inches of lift. Plus, they are designed to be compatible with your stock intake manifolds, exhaust systems, and even the temperature sensors on EFI models, making the installation process smoother. The natural aluminum finish gives a clean, classic look.

This set is a great choice for riders who want improved performance and are building out larger displacement engines. They fit a wide range of Harley-Davidson models, including the Electra Glide Classic, Heritage Softail Classic, and Dyna Super Glide, among many others. Be aware that these are not CARB approved and cannot be shipped to California.
