S&S Super Stock Head Kits


Harley Davidson Parts - S&S Super Stock  Head Kits

The high-quench combustion design and matched piston dome not only increase flow, but provide excellent flame travel which results in a more efficient and cleaner burn of the air/fuel mix. Therefore, a dual spark configuration for normal operation is not needed. The matching forged pistons that come with the S&S cylinder head package are complete with rings, wrist pins and wrist pin keepers. A special intake port and manifold design incorporates a directional vane, located in the floor of the port, that improves air flow by dividing and routing the air around the valve stem and guide. The manifold will accept 1 7/8" S&S, Bendix, Keihin (except CV) and other performance carburetors with 2 bolt flange-style mount. The different shape of the exhaust port also aids in the intake and expulsion processes and any exhaust system that can bolt up to stock heads will fit on the S&S heads because the exhaust port is located in the same position as stock. The valve train components are designed for use with cams with lifts to .570" and feature an inner flat wound damper spring designed to eliminate damaging vibration. “Super Stock” heads are sold as a complete system including pistons with rings, wrist pins and keepers, intake manifold with O-rings and flanges and fully assembled heads with valves, springs, collars and keepers all designed and readily bolt-on to fit like other stock components on Evolution® Big Twin models 1984–up (cylinders and flywheels are sold separately). Fits Evolution® Big Twin models 1984 thru 1999 with stock (4 1/4") stroke and stock (3 1/2") bore. 10.1:1 compression ratio.
