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 better resistance to corrosion compared to older gasket types. They are also designed to handle the shearing forces between different metal types, like aluminum heads and cast iron blocks, without needing extra sealants.

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

Viton is a heat-resistant synthetic rubber material, capable of withstanding temperatures up to 482°F (250°C). It's used as a coating on the outer layers of this gasket to ensure a strong seal in demanding engine environments and across various surface finishes.

Does this gasket come with any hardware or additional installation materials?

This product is for the Cometic MLS head gasket only. It is designed to be used without additional sealants, but you will need to refer to the manufacturer's installation instructions for any specific hardware or preparation requirements.

About this part

Product Details

Cometic Gasket is a well-known name for its multi-layer steel (MLS) head gaskets, built to handle the demands of high-output engines. This particular gasket is designed for Chrysler Gen-2 Hemi engines and features a 4.250-inch bore with a compressed operating thickness of 0.089 inches. It's constructed from multiple layers of stainless steel, with the outer layers coated in heat-resistant Viton rubber, making it suitable for sealing aluminum heads to both aluminum and cast iron blocks. These gaskets are built to withstand the stresses created by different metal types and don't require additional sealants.

The multi-layer steel construction provides increased strength and resistance to corrosion, while the embossed outer layers with Viton coating are designed to perform in harsh sealing environments. The center layer is stainless steel and can be varied to achieve different thickness requirements, like the 0.089-inch thickness found here. This gasket is a solid option for rebuilding or upgrading engines in a range of classic Mopar vehicles, including models like the Dodge Challenger, Dodge Charger, and Plymouth Barracuda from the late 60s and early 70s.
