Restore that tired iron! S&S has something for Shovelhead engines that are in need of a new top end. In a lot of cases it just isn’t worth it to try to rebuild the old, cracked, worn out cylinder heads or to bore the stock cylinders again. The S&S Shovelhead style top end kits provide everything you need to replace the top end of a 74“ or 80“ Shovelhead engine. They include pistons, rings, cylinders, cylinder heads, gaskets and hardware. Valves and springs are pre-installed and pistons are pre-fit to the cylinders, so there is no machine work to be done and very little down time. Kits for 74“ engines come with o-ring style cylinder heads, those for 80“ engines come with band style heads. Compression ratio for both top ends is 8:1. Since the kits are not interchangeable it is important to correctly identify the stroke of the engine before ordering.
