What is the compressed thickness of this head gasket?

This Cometic MLS head gasket has a compressed operating thickness of .045 inches. This measurement is important for ensuring proper valve-to-piston clearance and compression ratios.

Do I need to use any sealant with this gasket?

No, Cometic MLS head gaskets are designed to provide maximum sealing performance without the need for additional sealants. The Viton coating on the outer layers ensures a reliable seal on its own.

What does MLS stand for and why is it important?

MLS stands for Multi-Layer Steel. This construction uses multiple layers of stainless steel, which increases the gasket's strength, resilience, and resistance to corrosion, making it ideal for high-output engines.

About this part

Product Details

If you're working on the 4.6L 3-valve engine in your 2005-2010 Ford Mustang, this Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the job. It's designed to seal the combustion chamber effectively, ensuring your engine runs smoothly and efficiently. This gasket is specifically made for the RHS (Right Hand Side) of the engine and features a 94mm bore with a compressed thickness of .045 inches.

Cometic uses multiple layers of stainless steel for increased strength and resistance to corrosion, which is crucial for high-output engines. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and varying surface finishes, meaning you won't need any extra sealants. This construction makes it suitable for mating aluminum heads to either aluminum or cast iron blocks, as it can manage the different expansion rates between those metals.
