Cometic Chrysler B/RB .051in MLS Cylinder Head Gasket - 4.600in Bore - Siamese Bore

Starting with the embossed outer layers coated with Viton, this Cometic Multi-Layer Steel (MLS) head gasket is built for serious sealing performance. The Viton coating is a heat-resistant synthetic rubber that can handle temperatures up to 482 degrees Fahrenheit, making it ideal for the harsh environments found in high-output engines. This gasket is designed to provide maximum sealing without needing any additional sealants, which simplifies installation and ensures a clean job. It's well-suited for combinations of aluminum heads with either aluminum or cast iron blocks, as the multiple stainless steel layers can handle the shearing forces that can occur between dissimilar metals.

The multi-layer steel construction itself offers increased strength and resilience. These layers are designed to rebound and resist corrosion, giving you a durable seal that lasts. The center shim layer is uncoated stainless steel and can be varied to achieve different compressed thicknesses; in this case, the compressed operating thickness is 0.051 inches. This gasket is a solid option for a wide range of Chrysler B/RB engines found in vehicles like the Dodge Charger, Chrysler New Yorker, and Plymouth Barracuda from the late 1950s through the late 1970s.
