What does '.030in' mean for these gaskets?

The '.030in' indicates that these gaskets are .030 inches undersize compared to a standard gasket. This sizing is often used when engine components have been machined or resurfaced.

Do I need to use any sealant with these gaskets?

No, these Cometic MLS exhaust manifold gaskets do not require any sealants. The multi-layer steel design creates a reliable seal on its own, even with different combinations of head and manifold materials.

What kind of engines are these gaskets designed for?

These gaskets are specifically designed for Chevrolet Gen 1 Small Block V8 engines. They are built to handle the high cylinder pressures often found in these V8 powerplants.

Product Details

This is a set of Cometic Multi-Layer Steel (MLS) exhaust manifold gaskets, sized at .030 inches undersize. These gaskets are specifically made for Chevrolet Gen 1 Small Block V8 engines and are designed to handle extreme cylinder pressures. They are a solid option for rebuilding your top end or replacing worn-out gaskets, fitting a wide range of vehicles including Chevrolet C10 trucks, Camaro, and GMC C1500 models from the early to mid-80s.

Cometic's MLS design uses multiple layers of steel to create a strong seal that won't burn through or get pushed out, even under high cylinder pressures. They are built to withstand different combinations of cylinder head and exhaust manifold materials, which is common in modified engines. A key benefit is that they require no sealants, making installation more straightforward. These gaskets are also designed to resist corrosion and maintain their torque set over time, ensuring a reliable seal.
