750073 S S Shovelhead Cylinder Head Sets 1979 1984 Rubber Band Styl

If you are looking to bring your Shovelhead back to life, these S&S Cycle cylinder heads are a state-of-the-art solution. Designed to fit Big Twin models including FX, FXR, Softail, and Touring bikes from 1966 through 1984, these heads are sold as a set of front and rear. Unlike stock heads that use studs, S&S utilizes 5/16-18 hex-head bolts for the rocker boxes. They feature a directional vane in the intake ports to improve fuel-air flow and reduced exhaust valve diameters to prevent valve-to-valve interference with high-lift cams. These heads are fully assembled with premium valves, springs, and seals, and are compatible with modern unleaded fuels. They are available for both O-ring and rubber band style manifolds, ensuring a stock-like fit with improved performance.
