BBC Titan Copper Head Gasket 4.630 x .062

The BBC Titan Copper Head Gasket 4.630 x .062 by SCE Gaskets is designed for serious big-block Chevrolet builders and performance enthusiasts who require reliability under extreme cylinder pressures and temperatures. This gasket plays a crucial role in sealing combustion forces while managing thermal expansion across various thermal cycles.

Constructed from Titan copper, this gasket offers superior heat dissipation and longevity compared to traditional steel-core designs. The precise 4.630-inch bore diameter and .062-inch thickness are engineered to effectively seal BBC applications while ensuring optimal compression ring pressure and coolant flow throughout the combustion chamber.

This gasket is suitable for a range of BBC platforms, from mild 454 street builds to high-performance nitrous and supercharged applications. Its copper composition resists gasket creep and deformation, making it ideal for high-RPM and forced-induction environments where thermal cycling and boost pressure challenge gasket integrity.
