What is the primary benefit of using a Multi-Layer Steel (MLS) head gasket?

MLS head gaskets, like this Cometic C5329-053, are made from multiple layers of stainless steel. This construction provides superior strength and sealing capabilities compared to traditional composite gaskets, especially under high heat and pressure conditions common in Big Block V8 engines.

What does the Viton coating on the gasket do?

The Viton rubber coating on the outer layers of the gasket helps to create a more effective seal against the cylinder head and block surfaces. It's designed to withstand high temperatures, up to 482°F, and resist various fluids, ensuring a durable seal in demanding engine environments.

Does this gasket come with any installation hardware?

This product is for the Cometic cylinder head gasket only. It does not include head bolts or other installation hardware, which should be sourced separately if needed.

About this part

Product Details

If you're rebuilding the top end of your Chevrolet Mark-IV Big Block V8, a solid head gasket is crucial for a good seal. This Cometic MLS (Multi-Layer Steel) gasket is built for that job, offering a .053 inch thickness and a 4.375 inch bore diameter, making it suitable for a wide range of Chevrolet vehicles like the Impala, C10 Pickup, and Camaro from the mid-60s through the early 80s.

Cometic builds these gaskets with three to five layers of stainless steel. They use stainless steel because it's strong, resists corrosion, and has good rebound characteristics to maintain a tight seal. The outer layers are embossed and coated on both sides with Viton, a heat-resistant rubber material that can handle tough sealing environments and varying surface finishes. This Viton coating is good up to 482°F, so it's ready for the heat your big block can generate.
