Cometic Chrysler B/RB .098in MLS Cylinder Head Gasket - 4.600in Bore - Siamese Bore

When you're rebuilding the top end of your Chrysler B or RB engine, getting the cylinder head gasket seated right is crucial for sealing combustion. This Multi-Layer Steel (MLS) head gasket from Cometic is built for those high-output applications, featuring a compressed thickness of .098 inches and a 4.600-inch bore diameter, designed for Siamese bores.

Cometic uses multiple layers of stainless steel for strength and corrosion resistance, which also allows the gasket to rebound and maintain a seal. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that handles tough sealing environments and various surface finishes without needing additional sealants. This construction makes it suitable for mating aluminum heads to either aluminum or cast iron blocks, as it can manage the shearing forces between dissimilar metals.

This gasket is a solid option for a wide range of classic Chrysler, Dodge, and DeSoto vehicles from the late 50s through the late 70s, including models like the Chrysler New Yorker, Dodge Charger, and DeSoto Adventurer. Ensure you check the fitment data to confirm compatibility with your specific vehicle.
