Cometic Pontiac 326-455 CI V8 .043in Copper Exhaust Manifold Gasket Set - 2.000in x 1.550in D-Ports

This Cometic exhaust manifold gasket set is made with a .043 inch thick copper material, which is a solid choice for sealing your Pontiac V8's exhaust ports. The D-shaped ports measure 2.000 inches by 1.550 inches, designed to match up with many factory and aftermarket exhaust manifolds for Pontiac 326 to 455 cubic inch V8 engines.

These gaskets are built to handle the heat and pressure of exhaust systems without needing any additional sealants, making installation more straightforward. The copper construction offers good thermal conductivity and resilience, helping to maintain a tight seal under demanding conditions. This set is suitable for a range of vehicles, including models like the Pontiac Firebird, GTO, and LeMans, as well as some Buick and Oldsmobile applications from the 1970s.
