Exhaust Gaskets AMC V8 304-401

The REMFLEX Exhaust Gaskets for AMC V8 304-401 are precision-engineered header and manifold gaskets designed to seal the connection between your engine's exhaust ports and the header assembly. This pair features a 1.620 x 1.820 inch dog leg port configuration in durable graphite material, engineered specifically for AMC V8 engines in the 304 to 401 cubic inch displacement range. These gaskets prevent exhaust leaks that compromise engine efficiency and create unwanted noise.

Graphite gasket material offers superior thermal stability and recovery compared to standard asbestos-based gaskets, making it the preferred choice for high-heat exhaust applications. The dog leg port design matches the exact bolt hole pattern and port shape of AMC V8 manifolds, ensuring a proper seal without modification. The 1.620 x 1.820 inch dimensions correspond precisely to AMC's original port specifications, eliminating fitment issues common with generic replacement gaskets. This verified pairing ensures consistent sealing pressure across the gasket face through multiple thermal cycles.

Builders and mechanics restoring or maintaining classic AMC-powered vehicles rely on REMFLEX gaskets to eliminate exhaust leaks that develop when original equipment gaskets degrade. Whether you're addressing a persistent exhaust leak on a vintage Javelin, AMX, or Hornet, or building a period-correct engine bay, these gaskets deliver OEM-level fit without the premium OEM price point. The pair format means you have both sides covered in one purchase, reducing downtime and ensuring symmetrical sealing on both exhaust manifolds.
