SBF Titan Copper Head Gasket LH 4.060 x .043

The SBF Titan Copper Head Gasket LH 4.060 x .043 is a precision cylinder head gasket engineered for small block Ford engines requiring left-hand (driver-side) installation. This left-hand copper head gasket features a 4.060-inch bore diameter and 0.043-inch compression thickness, delivering the critical seal integrity that high-performance and rebuilt engines demand. Built from copper material, this gasket provides superior thermal conductivity and conformability compared to conventional compositions, making it ideal for naturally aspirated and lightly boosted small block Ford applications.

The 0.043-inch compression thickness is engineered to achieve the correct quench distance and combustion chamber volume for small block Ford cylinder heads, a critical factor in maximizing efficiency and preventing detonation. Copper construction excels at distributing heat away from the gasket sealing surfaces, reducing hot spots that can lead to gasket failure under sustained load. The 4.060-inch bore specification fits modern small block Ford performance heads and is commonly used in street, bracket racing, and marine engine builds. This is a single gasket (per unit sold), meaning you'll need two for a complete engine—one for each side of the block.

This gasket is intended for builders and technicians assembling or rebuilding small block Ford engines where precision bore diameter and compression thickness are critical specifications. Small block Ford cylinder head gasket selection depends on exact bore size and compression height; this left-hand version is specifically designed for driver-side installation. Verify your engine's exact bore diameter and required compression thickness before purchase, as incorrect specifications can result in poor sealing, cooling flow obstruction, or combustion chamber mismatch.

Small block Ford cylinder head gaskets are available in multiple bore sizes and compression thicknesses to accommodate different head casting families and compression ratios. The 4.060-inch bore is standard across many aftermarket performance cylinder head manufacturers. Copper head gaskets, while requiring careful installation technique and proper surface preparation, offer measurable advantages in thermal management and longevity compared to steel-core or composite alternatives in high-output applications.
