1.875 Dia. BBC Copper Embossed Exhaust Gasket

The 1.875 Dia. BBC Copper Embossed Exhaust Gasket (SCE Gaskets model 4013) is an essential component for ensuring a leak-free exhaust system in big-block Chevrolet engines. This gasket is designed to fit precisely at the junction where the exhaust manifold meets the header pipe, a critical area that requires reliable sealing to prevent costly repairs.

Engineered with copper embossing technology, this gasket provides a resilient seal capable of withstanding high temperatures and pressures. The 1.875-inch diameter bore is tailored to match BBC manifold flange specifications, while the copper material ensures durability under extreme thermal cycling. Its embossed design effectively grips mating surfaces, minimizing blow-by and vibration-induced creep, which are common causes of leaks.

This gasket is ideal for mechanics and engine builders working on various BBC applications, from classic muscle cars to modern LS conversions that utilize traditional manifold adapters. Its construction guarantees consistent clamp load retention across repeated heat cycles, making it a reliable choice for high-performance engines.
