S&S Cycle 79-84 BT Super Stock 3-5/8in Bore Band Style Single Plug Cylinder Head Kit - Natural

S&S Cycle is well-known for making performance engine parts for Harley-Davidson motorcycles. This Super Stock band style cylinder head kit is designed for 1979 through 1984 Big Twin models. While they look similar to stock heads, these are built to flow significantly better, giving your engine a noticeable boost in performance. They are machined to accept cylinders with a 3-5/8 inch bore and are set up for one spark plug per head, which is a common setup for many performance builds.

These heads come fully assembled with quality valves and S&S valve springs. The springs are strong enough to handle cams with lifts up to .590 inches, giving you flexibility if you decide to upgrade your camshaft down the road. They are the same heads used as original equipment on S&S SH-Series engines, making them a solid choice for upgrading your stock Shovelhead. A practical detail is that the rocker boxes attach with 5/16"-18 cap screws, which is a more secure method than the stock studs and nuts. This kit includes everything you need to get started: the front and rear cylinder head assemblies, rocker box gaskets, copper head gaskets, exhaust gaskets, all necessary hardware, and installation instructions. The natural aluminum finish gives a clean, classic look.
