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

Starting with a .043 inch thickness, these Cometic exhaust manifold gaskets are built with multiple layers of stainless steel. This multi-layer design offers increased strength and the ability to rebound, helping to resist leaks and corrosion in tough sealing environments. The outer layers are embossed and coated on both sides with Viton rubber, which can handle temperatures up to 482°F, making them suitable for a wide range of harsh conditions and surface finishes.

These gaskets are designed for Chevrolet Mark-IV and GM Gen-V/VI Big Block V8 engines, fitting a broad spectrum of vehicles from the 1960s through the 1980s, including popular models like the Chevrolet Impala, C10 Pickup, and Corvette. A key benefit is that they require no additional sealants, simplifying installation and ensuring a clean, reliable seal right out of the box.
