About This Product
Upgrade your early Twin Cam's breathing with this S&S SuperStock cylinder head kit. Finished in a durable black powder coat, these heads are a bolt-on performance replacement for 1999 to 2005 Twin Cam models. They feature 79cc combustion chambers and are equipped with 1.940-inch intake and 1.575-inch exhaust valves, capable of handling up to .650-inch lift. These heads are designed to work seamlessly with stock manifolds, exhausts, and rocker boxes, though they do require a specific rocker cover gasket. They come fully assembled with valves, guides, and springs already installed. Machined for compression releases, these heads are perfect for high-performance builds using S&S 510, 570, or 585 cams. This kit is sold as a set for a complete top-end transformation.
Manufacturer part number: 90-1293.
