Product Information
Suit 273 and 318 Small Block engines, suit factory exhaust manifold or Pacemaker extractors.

Unlike other competitors, we won't give you a fancy name, just the best exhaust gasket on the market.
Using this gasket you can be SURE it will SEAL every time!

Don’t bother with composite gaskets that simply don’t seal!
These gaskets have optimum "crush" value ensuring a tight seal especially good for extractors, but still able to be used on standard factory manifolds with same results!!

The gasket material is 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 ones can be opened up with die grinder for ported heads still have enough material to seal properly making them great for turbo / Supercharged applications....try them, you won’t go back to using inferior ones!
