Cometic Chrysler B/RB .045in MLS Cylinder Head Gasket - 4.600in Bore - Siamese Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built with a compressed operating thickness of 0.045 inches and a 4.600-inch bore, designed for Chrysler B/RB engines with siamese bores. MLS gaskets are constructed from multiple layers of stainless steel, which gives them increased strength and the ability to rebound, helping them resist corrosion and maintain a strong seal. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle harsh sealing environments and various surface finishes, making these gaskets ideal for both aluminum and cast iron blocks. They require no additional sealants, simplifying installation and ensuring a dependable seal for high-output engines.

The construction of this gasket, with its embossed outer layers and Viton coating, is specifically chosen to meet the demands of modern engines. The stainless steel layers provide a solid foundation, while the Viton coating ensures a tight seal against the cylinder head and block surfaces, even under high temperatures and pressures. This well-built gasket is suitable for a wide range of vehicles, including models like the Dodge Charger, Chrysler New Yorker, and Dodge D100 Pickup, offering a reliable sealing solution for many classic Mopar applications.
