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

MLS head gaskets are made of multiple stainless steel layers, which increases their strength and resistance to corrosion. They are designed to provide maximum sealing performance for high-output engines and can handle the stresses between different block and head materials.

Does this gasket require any sealant?

No, this Cometic MLS head gasket does not require any additional sealants. The Viton coating on the outer layers is designed to create a reliable seal on its own.

What is the operating thickness of this gasket?

The compressed operating thickness of this head gasket is 0.027 inches. This measurement is important for maintaining proper compression ratios and valve-to-piston clearance.

About this part

Product Details

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. It’s designed specifically for Chrysler Gen-2 Hemi engines with a 4.375-inch bore, offering a compressed thickness of 0.027 inches. This gasket is built to handle the demands of high-output engines, ensuring a reliable seal between your cylinder heads and engine block.

This MLS gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well in various sealing environments and on different surface finishes. This construction makes it suitable for pairings like aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, as it can manage the shearing forces that can occur between dissimilar metals. The center layer is also stainless steel and can be varied to achieve different thicknesses, like the 0.027 inches on this particular gasket.

This gasket fits a range of classic Mopar vehicles, including models like the Dodge Challenger, Dodge Charger, and Plymouth Barracuda from the late 60s and early 70s. Because it's an MLS design, it doesn't require any additional sealants, making installation more straightforward.
