SBF Copper Head Gasket RH 4.155 x .062

The SBF Copper Head Gasket RH 4.155 x .062 is a precision-engineered sealing component designed for small-block Ford (SBF) engine builds and rebuilds. This right-hand gasket serves as a critical barrier between the cylinder head and engine block, preventing combustion gases and coolant from leaking into the oil gallery and vice versa. Whether you're restoring a classic muscle car, building a performance 302, 351W, or preparing a street engine for serious duty, a quality copper head gasket is non-negotiable for reliable long-term operation.

Copper head gaskets remain the gold standard in performance engine building because copper conducts heat efficiently away from the combustion chamber while maintaining superior sealing integrity under extreme pressure and temperature cycling. The 4.155-inch bore diameter and .062-inch thickness specification make this gasket compatible with standard SBF configurations, and the copper construction resists corrosion and maintains a consistent seal across thousands of heat cycles. Unlike multi-layer steel (MLS) designs, copper gaskets compress and conform to minor surface irregularities on aging or hand-ported cylinder heads, a critical advantage when working with vintage castings or custom-modified surfaces.

This RH (right-hand) gasket is essential for complete SBF head gasket sets and suits engine builders, mechanics, and enthusiasts rebuilding or upgrading fuel-injected or carbureted small-block Fords. Installation requires proper cylinder head surface preparation—a light honing or steel-wooling to remove old gasket material and achieve a clean seating surface—followed by correct bolt torque sequencing for optimal compression and leak prevention. Pair this gasket with quality head bolts, a reliable torque wrench, and manufacturer-specified fastener patterns to ensure a professional-grade seal that will hold pressure and temperature for years of reliable street or strip use.
