S&S Cycle 79-84 BT Super Stock Stock Bore Band Style Single Plug Cylinder Head Kit

If you're looking to get more performance out of your 1979-1984 Harley-Davidson Big Twin, especially a Shovelhead, this S&S Cycle Super Stock cylinder head kit is a solid choice. These heads are designed to look like stock but flow significantly better, giving your engine a noticeable boost in power. They're a direct upgrade for stock 74" or 80" engines and are even the original equipment on S&S SH-Series engines.

What makes these heads stand out is their improved airflow compared to stock units. They come fully assembled with quality valves and S&S valve springs, which are strong enough to handle camshafts with lifts up to .590". This means you have more flexibility when choosing performance cams. The heads are set up for a single spark plug per cylinder, and they use 5/16"-18 cap screws to secure the rocker boxes, a more robust setup than the original studs and nuts. The natural aluminum finish keeps the classic look of your engine.

This kit is quite comprehensive, including everything you need to get these heads installed. You'll find both the front and rear cylinder head assemblies, rocker box gaskets, copper head gaskets, exhaust gaskets, and all the necessary hardware. Plus, it comes with instructions to guide you through the process. It's a well-built kit that offers a significant performance improvement while maintaining a stock appearance.
