Cometic Chrysler Gen-2 426 Hemi .040in MLS Cylinder Head Gasket-4.250in Bore-World Products Block

This is a Cometic Multi-Layer Steel (MLS) cylinder head gasket designed for Chrysler Gen-2 426 Hemi engines using a World Products block. It features a 4.250 inch bore and is 0.040 inches undersize, intended for engines that have been machined to that specification. MLS gaskets are built for high-output engines and provide excellent sealing without needing additional sealants, making them a solid choice for both aluminum and cast iron block combinations.

Cometic builds these gaskets with multiple stainless steel layers for increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and various surface finishes. The center layer is stainless steel and can be varied in thickness to meet specific engine build requirements; this particular gasket has a compressed operating thickness of 0.036 inches.

This gasket fits a range of classic Mopar vehicles from the late 60s and early 70s, including models like the Dodge Charger, Plymouth Barracuda, and Dodge Challenger. Always confirm fitment for your specific application.
