SBF Copper Head Gasket LH 4.060 x .050

The SBF Copper Head Gasket LH 4.060 x .050 from SCE Gaskets is a precision-engineered sealing component designed for small-block Ford engine builds and rebuilds. This left-hand gasket serves as the critical seal between the cylinder head and engine block, preventing combustion gases, coolant, and oil from escaping or mixing. Whether you're performing a stock rebuild, upgrading to aftermarket heads, or running a high-compression stroker, a quality copper head gasket is non-negotiable for reliability and longevity.

Copper gaskets are the preferred choice for serious engine builders because they excel under extreme heat and pressure cycles that conventional composite gaskets cannot withstand. The 4.060-inch bore diameter and .050-inch thickness are optimized for small-block Ford applications, ensuring proper clamping load distribution across the head surface. SCE's copper construction provides superior conformability to imperfect deck surfaces, reducing the risk of gasket failure and head lift common in modified engines.

The copper material also offers excellent thermal conductivity, helping dissipate heat away from critical sealing areas—a critical advantage when running forced induction, nitrous oxide, or aggressive ignition timing. This left-hand gasket is essential for dual-quad setups, crossflow heads, or any SBF configuration where head orientation demands a specific left-side gasket. Installation requires proper head bolt torque sequencing and a clean, smooth deck surface.
