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.

It includes: 4 1/8 in. bore pistons; big bore cylinders finished in wrinkle black powdercoat; a dynamically balanced 4 5/8 in. stroke 3-piece flywheel assembly complete with heavy-duty connecting rods and integral mainshafts; 640 gear drive Easy Start camshafts; chromoly steel adjustable pushrods; premium tappets; and Super Stock 91cc cylinder heads. When installed, the kits yield a 124 in. engine with a compression ratio of 11:1. Although the engine is .960 in. taller than stock, there are no frame clearance problems—and a stock EFI throttle body will fit, because the manifold mounting surfaces of the heads have been specially machined to fit a stock length manifold. If you ride a 2006 HD Dyna model, or a balanced or non-balanced Big Twin from 2007-17, these top-end engine rebuild kits are for you. Note: No fuel or ignition system is included. However, for the best results, a larger EFI throttle body, performance intake, and performance exhaust are recommended. The EFI system must be recalibrated. Although not mandatory, S&S recommends adding an oil cooler to bikes ridden in warmer climates. S&S does not recommend compression ratios higher than 10:1 for Tri Glide or other 3-wheel models (including conversions) due to extra loads caused by the lugging nature of these bikes. Detonation and subsequent engine damage may result.
