Cometic Chrysler 318/340/360 4.18in Bore .060in MLS-5 Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket is built with a compressed operating thickness of 0.060 inches, making it a solid choice for rebuilding or upgrading Chrysler LA V8 engines like the 318, 340, and 360. The multi-layer design uses embossed stainless steel for increased strength and resistance to corrosion, while the outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This construction ensures a reliable seal even under the demands of high-output engines, and it works well with both aluminum and cast iron blocks.

The Viton coating on the outer layers is designed to meet the challenges of harsh sealing environments and varying surface finishes, providing a robust seal without the need for additional sealants. The center shim layer is also stainless steel and can be varied to achieve different thickness requirements, like the 0.060 inches specified for this particular gasket. This gasket fits a wide range of vehicles, including classic models like the 1965 Bristol 408, the 1970 Dodge Challenger, and the 1978 Dodge D150.
