What does the .050in in the part number mean?

The .050in indicates that this gasket is 0.050 inches undersize. This means it's intended for engines that have had their cylinders bored out by 0.050 inches beyond the original factory specification.

Do I need to use any sealant with this gasket?

No, Cometic MLS head gaskets are designed to provide maximum sealing performance on their own and do not require any additional sealants. The embossed outer layers coated with Viton create a robust seal.

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

Viton is a type of heat-resistant synthetic rubber. It's used on the outer layers of this gasket because it can withstand high temperatures and harsh sealing environments, ensuring a durable and reliable seal between the cylinder head and the engine block.

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 demands of a high-output build. It's designed with a 4.500-inch bore and is 0.050 inches undersize, meaning it's intended for engines that have been bored out. This gasket fits a range of classic Mopar V8 applications, including models like the Dodge Charger, Plymouth Barracuda, and Dodge Challenger from the late 60s and early 70s.

Cometic's MLS gaskets are constructed from multiple layers of stainless steel, which gives them strength and the ability to rebound, helping to resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes, ensuring a solid seal without needing additional sealants. The center layer is stainless steel, and its thickness can be varied to achieve different compressed operating thicknesses; this particular gasket has a compressed thickness of 0.036 inches.
