Cometic Chrysler B/RB .066in MLS Cylinder Head Gasket - 4.600in Bore - Siamese Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed layers of stainless steel, featuring outer layers coated with Viton rubber. It's designed with a compressed operating thickness of 0.066 inches and a 4.600-inch bore, specifically for Siamese bore applications on Chrysler B/RB engines. MLS gaskets are known for providing maximum sealing performance, especially for high-output engines, and they don't require any additional sealants.

The strength of these MLS gaskets comes from their multiple stainless steel layers, which also allow them to rebound and resist corrosion. The Viton coating on the outer layers is a heat-resistant material capable of handling harsh sealing environments and varying load conditions. The center layer is uncoated stainless steel, allowing for different thickness requirements. This construction makes them suitable for pairings of aluminum heads with aluminum blocks, or aluminum heads with cast iron blocks, as they can handle the shearing forces between different materials.

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 DeSoto Adventurer. It's a solid option when you need reliable sealing for your engine rebuild.
