Cometic Chrysler Big Block B/RB V8 .043in Copper Exhaust Manifold Gasket Set-1.780in x 1.480in Port

When you're rebuilding or repairing the exhaust system on your Chrysler Big Block B/RB V8, getting a solid seal at the manifold is crucial. These Cometic exhaust manifold gaskets are designed to do just that, helping to prevent exhaust leaks and ensure your engine runs efficiently. They are built for a range of Chrysler and Dodge vehicles from the late 50s through the late 70s, including models like the Chrysler 300, Dodge Charger, and Dodge Coronet.

These gaskets are made from multi-layer steel (MLS) with a copper construction and feature Viton elastomer coating on both sides. This advanced construction means they don't require any additional sealants, making installation straightforward. The multi-layer design offers improved strength and resistance to shearing forces, especially when mating different metals like aluminum heads to cast iron blocks. The specific port dimensions are 1.780 inches by 1.480 inches, designed to match the factory exhaust port size for a proper fit.
