What is the main advantage of using an MLS head gasket?

Multi-Layer Steel (MLS) head gaskets offer superior sealing performance for high-output engines. They are built with multiple stainless steel layers for strength and corrosion resistance, and they don't require additional sealants.

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

Viton is a heat-resistant rubber material that can withstand high temperatures and harsh sealing environments. Coating the outer layers of the gasket with Viton ensures a dependable seal against the cylinder head and block surfaces.

Does this gasket come with any hardware or sealant?

This Cometic MLS head gasket is designed to provide maximum sealing performance on its own and does not require additional sealants. The package includes the head gasket itself; any necessary hardware would typically be purchased separately.

Product Details

When you're rebuilding a high-output Chevrolet Mark-IV Big Block V8, getting the cylinder head sealing just right is critical. This Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the demands of these powerful engines, ensuring a solid seal between your block and heads without needing extra sealants.

With a compressed thickness of 0.098 inches and a 4.375-inch bore, this gasket is designed for a precise fit and reliable performance in many Chevrolet applications from 1965 through the early 1990s, including models like the C10 Pickup, Impala, and Camaro.
