What is the advantage of a Multi-Layer Steel (MLS) head gasket?

MLS head gaskets are made of multiple stainless steel layers, which gives them increased strength and the ability to rebound. This construction helps them resist corrosion and maintain a strong seal under high-output engine conditions.

Does this gasket require any sealant?

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

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

Viton is a heat-resistant rubber material used to coat the outer layers of the gasket. It's chosen for its ability to withstand high temperatures and harsh sealing environments, ensuring durability and performance.

About this part

Product Details

If you're rebuilding the top end of your GM Gen-V or VI Big Block V8, a solid head gasket is crucial for sealing combustion pressure. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of high-output engines, ensuring a strong seal between your cylinder head and block.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. This design works well whether you're mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, as it can manage the shearing forces that can occur between different metals. The compressed thickness is .051 inches, and the bore size is 4.630 inches, designed for a precise fit on these specific big block V8s.

This gasket is designed for a direct fit on a wide range of Chevrolet and GMC trucks from the early 90s through the late 90s and early 2000s. Because it's an MLS gasket, it doesn't require any additional sealants, simplifying the installation process.
