What is the compressed thickness of this head gasket?

When properly installed and compressed, this Cometic head gasket has an operating thickness of 0.075 inches. This specific thickness is important for achieving the correct compression ratio in your engine build.

Do I need to use any sealant with this head gasket?

No, Cometic MLS head gaskets are designed to provide maximum sealing performance on their own and do not require any additional sealants. The Viton coating on the outer layers helps create a reliable seal.

What is the difference between LHS and RHS head gaskets?

LHS stands for Left Hand Side and RHS stands for Right Hand Side. When installing head gaskets on a V-engine like the Hemi, you typically need a specific gasket for each bank of cylinders to ensure proper fitment and sealing.

About this part

Product Details

This is a Cometic Multi-Layer Steel (MLS) head gasket, specifically made for Chrysler's 6.4L Apache Gen-3 Hemi engines. It has a 4.120-inch bore and a compressed thickness of 0.075 inches. These gaskets are built for high-output engines and are designed to provide a strong seal without needing extra sealants, making them a solid choice for rebuilding or upgrading your engine.

Cometic uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and various surface finishes. This construction helps them withstand the forces created when mating aluminum heads to either aluminum or cast iron blocks. The center layer is stainless steel and can be varied to achieve different gasket thicknesses, like this 0.075-inch version, which is ideal for specific engine builds.

This gasket fits a range of vehicles including the Dodge Challenger, Dodge Charger, and Jeep Grand Cherokee. It's a well-built component for anyone working on these powerful Hemi engines.
