Pro Copper Exhaust Gaskets - HEMI

The Pro Copper Exhaust Gaskets – HEMI by SCE Gaskets are precision-engineered sealing components designed for high-performance Mopar 426 HEMI applications. These gaskets are engineered to prevent exhaust leaks at the header-to-cylinder-head interface, a critical junction that experiences extreme thermal cycling and pressure fluctuations. Built for enthusiasts and professionals who demand reliability in street and competition engines, the Pro Copper Exhaust Gaskets deliver proven durability where factory gaskets often fail under sustained performance demands.

Manufactured from premium copper material, these gaskets feature 1.745-inch stock port geometry to match OEM HEMI specifications precisely. Copper's superior thermal conductivity and malleability allow the gasket to conform to both the exhaust manifold and cylinder head surfaces, creating a gas-tight seal even as engine temperature and pressure vary. The Pro series designation indicates enhanced durability and heat resistance compared to standard alternatives, making them suitable for forced-induction builds, high-RPM operation, and extended track use. This gasket pair weighs 0.94 lbs and maintains consistent performance across the wide temperature range typical of modern HEMI engines.

The Pro Copper Exhaust Gaskets are ideal for Mopar 426 HEMI owners upgrading to custom or performance headers, or replacing original equipment that has degraded from heat cycling. Installation is straightforward—simply position the gaskets at the header mounting surface and secure with factory bolts. These gaskets are sold as a pair, covering both exhaust ports on the engine. Proper gasket selection eliminates exhaust leaks that rob power, create noise, and introduce unburned gases into the engine bay.
