BBC ISC Titan Copper Head Gskt 4.570 x .043

The BBC ISC Titan Copper Head Gskt 4.570 x .043 from SCE GASKETS is a precision cylinder head gasket engineered for big block Chevy engines demanding maximum reliability and heat resistance. Built for serious engine builders, performance mechanics, and enthusiasts running high-compression or boosted applications, this copper gasket delivers the durability required when standard gaskets fall short. Whether you're rebuilding a classic muscle car engine, upgrading a street performance build, or assembling a competition powerplant, this head gasket is designed to seal and hold under extreme conditions.

Constructed from premium copper with a 0.043-inch compression thickness, the BBC ISC Titan gasket provides superior heat dissipation and conformability compared to conventional steel gaskets—critical advantages when cylinder pressures spike from forced induction, high RPM operation, or aggressive combustion chamber design. The 4.570-inch bore specification matches precision big block Chevy applications, ensuring proper sealing surface contact and eliminating guesswork during head installation. Copper composition allows the gasket to expand and contract uniformly with engine temperature cycling, reducing the risk of blowby, coolant leaks, or combustion gas escape—common failure modes in high-performance engines where metal-to-metal contact is less forgiving.

This gasket is ideal for builders working with big block Chevy platforms including BBC 454, 427, and other large-displacement variants where OEM gaskets cannot withstand sustained boost, nitrous oxide, or extended high-RPM duty cycles. Installation requires standard head torque procedures; ensure cylinder deck and head mating surfaces are clean and properly honed before assembly. Each gasket ships individually, making it suitable for single-engine builds or as a replacement component when upgrading existing powerplants to copper construction for increased margin of safety.
