Cometic Chrysler 361/383/413/440 4.410 inch Bore .040in MLS Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket is built with a compressed operating thickness of 0.040 inches and a 4.410-inch bore, making it a solid choice for rebuilding or maintaining Chrysler B and RB series V8 engines. These gaskets are designed to handle the demands of high-output applications, offering improved sealing performance over traditional composite gaskets.

The construction features multiple layers of stainless steel for added strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material capable of withstanding temperatures up to 482 degrees Fahrenheit. This Viton coating ensures a reliable seal even in harsh environments and across different surface finishes, and it works well when mating aluminum heads to either aluminum or cast iron blocks. The center shim layer is uncoated stainless steel, allowing for precise thickness control.

Because these MLS gaskets are designed for maximum sealing, they typically do not require any additional sealants. This gasket fits a wide range of Chrysler, Dodge, and DeSoto vehicles from the late 1950s through the late 1970s, including models like the Chrysler New Yorker, Dodge Charger, and Dodge D100 Pickup.
