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

MLS head gaskets are constructed from multiple layers of stainless steel, which provides superior strength and resilience compared to single-layer gaskets. This construction allows them to rebound effectively and resist corrosion, making them ideal for high-output engines.

What is Viton and why is it used on this gasket?

Viton is a type of synthetic rubber known for its excellent heat resistance, capable of withstanding temperatures up to 482 degrees Fahrenheit. It's used as a coating on the outer layers of this gasket to ensure a reliable seal in demanding engine environments.

Do I need to use any sealant with this head gasket?

No, Cometic MLS head gaskets are designed to provide maximum sealing performance without the need for additional sealants. The advanced materials and construction typically create a sufficient seal on their own.

About this part

Product Details

Starting with a compressed thickness of 0.036 inches, this Cometic Multi-Layer Steel (MLS) head gasket is built for serious sealing performance. It's designed to handle the demands of high-output engines, whether you're pairing aluminum heads with aluminum blocks or aluminum heads with cast iron blocks. The MLS construction uses multiple layers of stainless steel, which not only adds strength but also allows the gasket to rebound and resist corrosion. This makes it a solid choice for engines that push the limits.

The outer layers of this gasket are coated on both sides with Viton, a heat-resistant rubber material rated up to 482 degrees Fahrenheit. Viton is known for its ability to hold up in harsh sealing environments and under various load conditions. The center layer is uncoated stainless steel, and its thickness can be varied to meet different requirements, like this gasket's .075-inch uncompressed thickness. Because they are well-built with these advanced materials, Cometic MLS gaskets typically don't require any additional sealants, simplifying installation.

This gasket is a popular choice for a wide range of vehicles, including many GM, Chevrolet, GMC, Buick, and Avanti models from the 1980s and 1990s. It's designed to fit right and provide reliable sealing for your engine build.
