SBF Copper Head Gasket RH 4.060 x .043

The SCE Gaskets SBF Copper Head Gasket RH 4.060 x .043 is a professional-grade cylinder head gasket engineered for Small Block Ford engines. This right-hand passenger-side gasket features copper construction and a 0.043-inch compression thickness, designed to maintain reliable sealing under high combustion pressures in performance and street applications.

The 4.060-inch bore specification matches factory and overbored Small Block Ford cylinder heads, providing precise fitment for rebuild, performance upgrade, and race engine applications. Copper head gaskets offer superior thermal conductivity compared to composition alternatives, allowing heat to transfer more efficiently from the combustion chamber to the cooling system. This thermal management characteristic is particularly valuable in high-horsepower builds where peak cylinder temperatures can exceed standard operating ranges. The 0.043-inch compression thickness is a critical specification that directly influences combustion chamber volume, quench height, and overall engine tuning parameters—precision here ensures your compression ratio targets are met as designed.

This gasket is intended for enthusiasts and professionals rebuilding or refreshing Small Block Ford engines, including 289, 302, 351W, and related displacement variants. Whether you're performing a basic overhaul, transitioning to higher boost or boost pressure levels, or assembling a dedicated race engine, proper head gasket selection is fundamental to engine reliability and longevity. The right-hand designation ensures correct application to the passenger side of the engine block, critical for dual-gasket or complete engine rebuild scenarios where both sides require replacement.
