SCE Graph-Form premium header gaskets feature an extra-thick design so they can conform to warped or pitted header and exhaust system sealing surfaces as much as 1/16 in. out of tolerance. Proprietary Graph-Form material outperforms all competing brands for high-temperature sealing. These premium header gaskets are made of an exclusive high-density, super hi-temp graphite—and require only basic port shape similarity. They seal as well as copper, but offer easier fitment.
