What does MLS mean for a head gasket?

MLS stands for Multi-Layer Steel. It means the gasket is made of several layers of stainless steel pressed together. This construction offers improved strength and sealing capabilities compared to older gasket designs.

What is the Viton coating for?

The Viton coating on the outer layers helps create a strong seal between the cylinder head and the engine block. It's heat resistant up to 482°F (250°C) and can handle various sealing environments and surface finishes.

Does this gasket come with any hardware?

This product is for the head gasket only. It does not include head bolts or other installation hardware. You will need to source those separately if required for your rebuild.

About this part

Product Details

If you're rebuilding the top end of your Chevy Gen 1 Small Block V8, a solid head gasket is crucial for a good seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the pressures and temperatures of these engines. It's designed for a 4.100 inch bore and features an 18/23 degree valve pocketed bore, ensuring it lines up correctly with your cylinder head's combustion chamber shape.

Cometic uses multiple layers of stainless steel for this gasket, which gives it extra strength and helps it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This coating helps create a reliable seal, even in demanding conditions and on surfaces that aren't perfectly smooth. This gasket fits a wide range of vehicles, including many Chevrolet C10 and Camaro models from the 1980s.
