BBC ISC Titan Copper Head Gskt 4.630 x .043

The BBC ISC Titan Copper Head Gasket with a 4.630" bore and .043" thickness is designed for serious big-block Chevy builders and engine shops that are working with naturally aspirated or moderately boosted engines. This gasket is essential for creating a reliable seal between the cylinder head and block, where high combustion pressures and thermal cycling are present.

Constructed from a 100% copper core with elastomer facing, the Titan Copper formulation provides superior heat dissipation and thermal conductivity compared to standard composite gaskets. The .043" thickness is specifically optimized for ISC (Iron Seal Coating) applications, ensuring consistent clamp load retention and minimizing gasket creep during high-RPM operation.

This gasket is ideal for BBC engine builders, machine shops, and automotive enthusiasts who are rebuilding or enhancing performance in their engines. Its malleability allows it to conform to minor irregularities in head and block surfaces, effectively sealing against blowby and coolant leaks.
