What makes a Multi-Layer Steel (MLS) head gasket different from a composite gasket?

MLS gaskets use multiple layers of stainless steel for superior strength and sealing compared to traditional composite gaskets. The stainless steel provides better resistance to heat and pressure, while the embossed and coated outer layers ensure a tight seal against the engine block and cylinder head.

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

Viton is a type of synthetic rubber known for its excellent resistance to high temperatures and harsh chemicals. Coating the outer layers of the gasket with Viton helps it maintain a strong seal in demanding engine environments, resisting degradation from heat and engine fluids.

Does this gasket come with all the necessary hardware for installation?

This product is for the cylinder head gasket only. It does not include head bolts or other installation hardware. It is recommended to refer to the manufacturer's installation instructions for a complete list of required components and procedures.

About this part

Product Details

If you're rebuilding the top end of your Chrysler LA V8 engine, you need a head gasket that can handle the job. This Multi-Layer Steel (MLS) gasket from Cometic is built for that purpose. It's designed to seal effectively in a variety of demanding conditions, ensuring your engine runs smoothly and reliably. The .030 inch thickness and 4.180 inch bore diameter are specific to certain LA V8 applications, so make sure it matches your build.

Cometic constructs these gaskets with three to five layers of stainless steel. This material choice gives the gasket strength and helps it resist corrosion and rebound well under pressure. The outer layers are embossed and then coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This combination of stainless steel and Viton coating helps create a solid seal, even with different surface finishes and load conditions on your engine block and heads.

This gasket fits a wide range of Chrysler, Dodge, and Plymouth V8 vehicles from the mid-60s through the early 90s, including models like the Chrysler Cordoba, Dodge D150, and Plymouth Barracuda. Always double-check the fitment data to ensure it's the right part for your specific vehicle and engine build.
