Cometic Chrysler B/RB V8 .045in MLS Cylinder Head Gasket - 4.500in Bore

When you're rebuilding or refreshing the top end of your Chrysler B/RB V8 engine, you'll need a reliable head gasket to seal the combustion chambers. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of higher output engines. It's designed to provide a strong seal without needing any additional sealants, making installation more straightforward.

This gasket is constructed with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material capable of withstanding temperatures up to 482°F (250°C), which is crucial for sealing in harsh engine environments. The center layer is stainless steel and can be varied in thickness; in this case, it's set to achieve a compressed operating thickness of 0.045 inches with a 4.500-inch bore, matching the specifications for your B/RB V8. This construction makes it suitable for use with both aluminum and cast iron blocks and heads.

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. Ensure you have a clean and flat mating surface on both the block and cylinder heads before installation for optimal sealing performance.
