Overview
Perfect for use with factory manifold or Pacemaker extractors.
This exclusive gasket is designed for use on Chrysler Big Block engines (361ci, 383ci, 400ci, 440ci.)
HP Premium Graphite Manifold Gaskets
These gaskets offer a superior seal when compared to traditional composite type. They have an optimum 'crush' value ensuring a tight seal; this is especially good for extractors, but still able to be used on standard factory manifolds with great results!
Made from a perforated stainless steel insert sandwiched between two layers of flexible graphite to ensure that they have a super high heat tolerance like no other aftermarket gasket.
These gaskets can be opened up with a die grinder for ported heads and still maintain enough material to seal properly. This makes them ideal for turbo & supercharged applications.
