Cometic AMC 304-401CI V8 .043in Copper Exhaust Manifold Gasket Set - 1.880in Dogleg Ports

Starting with a .043 inch thickness, this Cometic exhaust manifold gasket set is built to handle the demands of AMC 304-401CI V8 engines. The copper construction offers excellent thermal conductivity and malleability, helping it conform to the exhaust manifold and cylinder head surfaces for a strong, leak-free seal. These gaskets are designed with 1.880 inch dogleg ports, specifically shaped to match the exhaust port configuration on many AMC V8 applications, ensuring proper flow and preventing leaks.

Cometic uses a multi-layer steel (MLS) construction for these gaskets, with outer layers embossed and coated with heat-resistant Viton. This advanced design helps the gasket withstand the high temperatures and pressures found in exhaust systems, while the stainless steel center layer provides the necessary rigidity and allows for precise thickness control. This means you get a gasket that is both durable and effective at sealing, even with aluminum heads and cast iron blocks, without needing additional sealants.

This gasket set fits a range of vehicles, including American Motors Ambassador, Javelin, and Matador models, as well as Jeep Cherokee, J10, J20, and Wagoneer models from the 1970s. It's a solid option for anyone rebuilding or repairing the exhaust system on these classic V8 engines.
