What is the main advantage of Multi-Layer Steel (MLS) head gaskets?

MLS head gaskets offer increased strength and durability due to their layered stainless steel construction. They also provide excellent resistance to corrosion and can withstand higher pressures and temperatures compared to traditional gaskets.

Does this Cometic head gasket require any sealant?

No, this Cometic MLS head gasket is designed to provide maximum sealing performance without the need for any additional sealants. The Viton coating on the outer layers ensures a tight seal on its own.

What is the significance of the .050 inch thickness?

The .050 inch is the uncompressed thickness of the gasket. When installed, it compresses to 0.036 inches, which is a critical dimension for maintaining proper compression ratios and valve-to-piston clearance in your engine build.

About this part

Product Details

Starting with a compressed operating thickness of 0.036 inches, this Cometic Multi-Layer Steel (MLS) head gasket is built for serious sealing. It's designed for Chevrolet Gen-1 Small Block V8 engines and features a 4.060 inch bore, specifically suited for heads with 18 or 23 degree valve angles. This gasket is a solid choice for high-output engines where reliable sealing is critical.

The construction uses multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. This design means the gasket doesn't require any additional sealants, making installation more straightforward. It's also well-suited for combinations of aluminum heads with aluminum blocks or aluminum heads with cast iron blocks, as it can manage the shearing forces that can occur between different metals.

This gasket fits a wide range of vehicles from the early 1980s through the mid-1990s, including popular models like the Chevrolet C10 and Camaro, as well as GMC C1500 trucks. It's a well-built component designed to maintain seal integrity under demanding conditions.
