S&S Cycle Performance Replacement Cylinder Heads
S&S Cycle Performance cylinder heads are replacements for Big Twin engines. Designed to be compatible with a stock-style flat topped piston, their larger than stock intake and exhaust valves provide plenty of air while maintaining port velocity for good low and midrange response, while the S&S high-lift valve springs allow the installation of cams with up to .585 in. lift. S&S Cycle Performance cylinder heads are compatible with stock intake manifolds, exhaust systems, and temperature sensors for EFI-equipped models. Select low or standard compression heads with a natural aluminum or wrinkle black powdercoat finish for your Big Twin engine.
* Low compression sets have a slightly larger 82cc combustion chamber, making them ideal for larger displacement applications, producing a manageable compression ratio. These heads are original equipment on S&S V96 and V80 engines.
* Standard compression sets have a 76cc combustion chamber that gives a slight increase in compression for great results with most performance cams.
