Cometic Chrysler B/RB .040in MLS Cylinder Head Gasket - 4.600in Bore - Siamese Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built for Chrysler B/RB engines with a 4.600-inch bore and Siamese bores. It's designed to handle the demands of high-output engines, offering maximum sealing performance without needing additional sealants. This gasket is a solid option for builds using aluminum heads with either aluminum or cast iron blocks, as its construction can manage the shearing forces between different metals.

The gasket is constructed from multiple layers of stainless steel for increased 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°F (250°C). This coating is engineered to perform well in harsh sealing environments and under various load conditions. The center layer is uncoated stainless steel, and its thickness can be varied to meet different requirements, with this specific gasket having a compressed operating thickness of 0.040 inches.

This gasket fits a wide range of Chrysler, Dodge, and Plymouth vehicles from the late 1950s through the late 1970s, including models like the Chrysler New Yorker, Dodge Charger, and Plymouth Barracuda. It's a well-built component designed for reliable sealing in performance applications.
