Cometic Chrysler B/RB .027in MLS Cylinder Head Gasket - 4.600in Bore - Siamese Bore

Cometic Gasket is known for making well-built sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example. It's designed for Chrysler B/RB engines with a 4.600-inch bore and Siamese bores, offering a compressed operating thickness of 0.027 inches. This gasket is built to handle the demands of high-output engines, whether you're pairing aluminum heads with an aluminum block or aluminum heads with a cast iron block, as it can withstand the shearing forces that can occur between different metals.

The construction features 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 that can handle temperatures up to 482 degrees Fahrenheit and various sealing challenges. The center layer is also stainless steel and can be varied to achieve different thicknesses, making this a versatile option for engine builds. Because it's an MLS gasket, it doesn't require any additional sealants, simplifying installation.

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 for anyone rebuilding or working on these classic Mopar engines.
