What is the compressed thickness of this head gasket?

This Cometic Multi-Layer Steel head gasket has a compressed operating thickness of 0.120 inches. This measurement is critical for maintaining proper compression ratios and valve-to-piston clearance.

Do I need to use any sealant with this gasket?

No, this Cometic MLS head gasket is designed to provide maximum sealing performance on its own. The embossed outer layers coated with Viton create a tight seal without the need for additional sealants.

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

Viton is a type of heat-resistant synthetic rubber that can withstand high temperatures, up to 482 degrees Fahrenheit. It's used on the outer layers of this gasket to ensure a durable and reliable seal in the demanding environment of a high-output engine.

About this part

Product Details

If you're working on a Chrysler Gen-2 Hemi engine, this Cometic Multi-Layer Steel (MLS) head gasket is built to handle the job. It's designed with a 4.375-inch bore and a compressed thickness of 0.120 inches, making it a solid option for a range of classic Mopar muscle cars like the Dodge Charger, Plymouth Barracuda, and Dodge Challenger from the late 60s and early 70s.

What makes these MLS gaskets stand out is their construction. They're made from multiple layers of stainless steel, which gives them increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This advanced design means the gasket seals tightly without needing any extra sealants, and it can handle the differences in expansion between aluminum heads and cast iron blocks, which is common in these engines. The center layer is stainless steel and can be varied to achieve different thicknesses, but this specific gasket is set at 0.120 inches compressed.
