Cometic Chrysler B/RB .056in MLS Cylinder Head Gasket - 4.600in Bore - Siamese Bore

This product is a Cometic Multi-Layer Steel (MLS) cylinder head gasket designed for Chrysler B/RB engines with a 4.600-inch bore and Siamese bores. It's built with multiple embossed layers of stainless steel, and the outer layers have a Viton rubber coating. This construction helps provide a strong seal for high-output engines without needing additional sealants. MLS gaskets are well-suited for applications where aluminum heads meet aluminum or cast iron blocks, as they can handle the shearing forces that can occur between different materials.

The multiple stainless steel layers give this gasket increased strength and the ability to rebound, while also resisting corrosion. The Viton coating on the outer layers is a heat-resistant material designed to perform in demanding sealing environments, under various load conditions, and on different surface finishes. The center layer is uncoated stainless steel and can be varied in thickness to meet different requirements, with this specific gasket having a compressed operating thickness of 0.036 inches.

This gasket fits a range of vehicles, including models like the 1969-1974 Bristol 411, 1959-1971 Chrysler 300, and 1966-1978 Dodge Charger. It's a solid option for rebuilding or working on the top end of these engines.
