SBC Copper Head Gasket 4.155 x .043

The SBC Copper Head Gasket 4.155 x .043 from SCE Gaskets is a precision-engineered sealing component specifically designed for small-block Chevrolet (SBC) engine builds and rebuilds. This gasket is essential for both enthusiasts and professional engine builders who require reliable cylinder head sealing in high-performance or stock-displacement applications. Proper head gasket selection is crucial for maintaining combustion chamber integrity and overall engine longevity.

Featuring a 4.155-inch bore diameter and a .043-inch thickness, this copper head gasket ensures optimal sealing surface contact and accurate combustion chamber volume calculations. The copper construction offers superior thermal conductivity and conformability compared to traditional steel gaskets, allowing for uniform compression across the cylinder head deck and block surface. This design helps maintain precise valve timing geometry and piston-to-valve clearance.

This gasket is suitable for both street and competition small-block Chevrolet engines with displacement ranges from 283 to 406 cubic inches, provided that the cylinder head and block deck surfaces are properly machined and cleaned. Engine builders will appreciate the consistent clamp load distribution across all eight cylinders, which is vital for performance and reliability in various applications.
