What is the main advantage of Multi-Layer Steel (MLS) head gaskets?

MLS head gaskets are made from multiple layers of stainless steel, which gives them increased strength and resistance to corrosion. This construction also allows them to rebound and maintain a strong seal under high pressure and temperature conditions.

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

No, this Cometic MLS head gasket is designed to provide maximum sealing performance without the need for additional sealants. The Viton rubber coating on the outer layers ensures a tight seal against the engine block and cylinder head surfaces.

What is the significance of the .027 inch thickness?

The .027 inch thickness refers to the center shim layer of the gasket. This dimension, along with the overall compressed thickness of .098 inches, is important for maintaining the correct compression ratio in your 5.7L Hemi engine. Always confirm this is the correct thickness for your specific build or repair.

About this part

Product Details

If you're rebuilding the top end of your Dodge 5.7L Hemi, whether it's for a performance build or just routine maintenance, a solid head gasket is crucial. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of these popular engines, fitting a wide range of vehicles like the Dodge Charger, Challenger, Ram trucks, and Jeep Grand Cherokee.

Cometic uses multiple layers of stainless steel for strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that seals exceptionally well against aluminum or cast iron blocks, even with aluminum heads. This construction means you don't need extra sealants, and the gasket can handle the stresses between different metal types. The compressed thickness is .098 inches, with the shim layer being .027 inches thick, designed to maintain proper compression ratios for many 5.7L Hemi applications.

This gasket is a well-built option for anyone looking for reliable sealing in their Hemi engine. Make sure to check your specific engine's bore size and required gasket thickness to ensure this is the right fit for your project.
