SBC Copper Head Gasket 4.155 x .062

The SCE Gaskets SBC Copper Head Gasket 4.155 x .062 is a pro-grade cylinder head gasket engineered specifically for small block Chevy applications. This copper construction gasket delivers the sealing integrity and thermal stability required in high-compression and performance engine builds where reliability under sustained heat and pressure is non-negotiable.

The 4.155-inch bore diameter accommodates standard and popular small block Chevy displacement variants, while the 0.062-inch compression thickness is engineered to achieve proper combustion chamber geometry in stroker and overbore configurations. Copper gaskets exhibit superior thermal conductivity compared to composite materials, allowing heat to transfer more efficiently from the cylinder head to the block, reducing hot spots that can lead to detonation and premature wear. This material choice is favored in modified and racing applications where cylinder head temperatures run consistently elevated.

This gasket is ideal for engine builders and performance enthusiasts restoring or upgrading small block Chevy powerplants. Whether preparing an engine for street performance, bracket racing, or high-output cruise builds, this head gasket supports the demands of elevated boost, nitrous oxide systems, or aggressive carburetor tuning. Installation requires proper head bolt torque sequencing and application of appropriate sealant per engine builder specifications to maximize gasket life and prevent combustion gas or coolant seepage.
