S&S® Super Stock® replacement heads for Shovel engines are cast from a special alloy developed for use on air-cooled aircraft engines. Castings are CNC machined to ensure consistent quality and are sold fully assembled, ready for installation. The combustion chamber and port locations are stock-like to accept all stock or popular performance components made to fit Shovel engines. Heads are sold with valves, guides, seals and .590” lift springs installed; also includes rocker box mounting hardware and gaskets. Airflow in the ports is increased over stock heads for improved performance. Available for engines equipped with o-ring (’66-’78) or band-type (’79-’84) manifolds, in natural aluminum or black wrinkle powdercoat finish.
