Cometic Pontiac 326/350/389/400/421/428/455 V8 .043in Copper Exhaust Manifold Gasket Set

If you're working on a Pontiac V8 engine, like those found in a GTO, Firebird, or Grand Prix from the late 60s through the late 70s, these Cometic exhaust manifold gaskets are a solid choice. They're designed to seal the connection between your exhaust manifolds and the cylinder heads, which is crucial for keeping exhaust gases contained and preventing leaks that can affect performance and sound.

These gaskets are made with multiple layers of stainless steel, giving them strength and the ability to rebound under pressure. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This construction helps them seal effectively even in tough conditions and on surfaces that aren't perfectly smooth. A notable benefit is that they don't require any additional sealants, making installation more straightforward.
