SBC ISC Titan Copper Hd Gasket 4.200 x .050

The SBC ISC Titan Copper HD gasket 4.200 x .050 is purpose-built for small-block Chevrolet applications requiring premium head sealing under high-compression and boost environments. This gasket addresses the critical challenge facing engine builders: maintaining a reliable seal between cylinder head and block during sustained power delivery, whether you're running a street performance build, circle track application, or forced-induction setup.

SCE Gaskets engineered this product for builders who refuse to compromise on reliability, making it the go-to choice for serious SBC modifications. The Titan Copper construction delivers superior thermal conductivity and heat dissipation compared to standard composite gaskets, pulling combustion chamber heat away from the gasket sealing surfaces and reducing the risk of blow-by at peak cylinder pressures. The .050-inch thickness provides optimal gasket crush and recovery, maintaining consistent clamping load across bore variations.

This gasket excels in combination with aftermarket SBC heads, tunnel-ram intakes, and solid-roller cam combinations where stock gaskets fail under extreme conditions. The 4.200-inch bore diameter accommodates oversized ISC head designs common in high-displacement builds, ensuring compatibility and performance in demanding applications.
