SBF Copper Head Gasket LH 4.160 x .050

The SCE GASKETS SBF Copper Head Gasket LH 4.160 x .050 is purpose-built for Small Block Ford engine builders and performance mechanics seeking reliable compression sealing on the driver side. This copper construction head gasket is engineered to handle the demands of modified and high-performance SBF applications where stock gaskets fall short. Whether you're rebuilding a 289, 302, or 351W with aggressive cam profiles, forced induction, or nitrous oxide, a quality copper head gasket serves as the critical seal between your cylinder head and block.

Copper gaskets offer superior heat transfer and conformability compared to conventional steel-core designs, making them the choice for engines running elevated boost pressures or sustained high RPM. The 4.160-inch bore specification is optimized for ported and blueprinted Small Block Ford cylinder heads, while the 0.050-inch compression thickness provides the ideal stack height for common aftermarket head combinations and custom piston-to-valve clearance requirements. SCE's manufacturing standards ensure consistent density and edge sealing geometry, preventing hot spot leakage and combustion gas bypass that plague inferior gaskets in aggressive builds.

Installers should verify bore diameter and compression height against your specific head casting and piston package before ordering, as SBF variants and aftermarket heads sometimes require different specifications. This left-hand driver side gasket pairs with a corresponding right-hand gasket for complete engine sealing. Best results come from proper head bolt torque sequencing, quality fasteners, and a clean, resurfaced deck surface—standard practice for any engine destined for reliability under boost or high-output naturally aspirated conditions.
