Cometic Chevrolet Mark-IV GM Gen-V/VI Big Block V8 .043in Copper Exhaust Manifold Gasket

This is a set of Cometic copper exhaust manifold gaskets for Chevrolet Mark-IV, GM Gen-V/VI Big Block V8 engines. You get the gaskets needed to seal your exhaust manifolds to the cylinder heads. These gaskets are designed to handle the tough conditions of exhaust sealing, helping to prevent leaks and maintain proper engine performance.

Cometic builds these gaskets with multiple layers of stainless steel for strength and resistance to corrosion. The outer layers are coated with Viton rubber, which can handle temperatures up to 482°F (250°C) and works well in various sealing environments. The gasket material is also designed to compress and seal even on surfaces that aren't perfectly flat, which is common when dealing with older exhaust components. This makes them a solid option for rebuilding or repairing your exhaust system.

This gasket set fits a wide range of Chevrolet and GM vehicles from the mid-60s through the early 80s, including models like the Chevrolet Impala, C10 Pickup, and Corvette. Always refer to the fitment chart to confirm compatibility with your specific vehicle.
