SCE Gaskets Graph-Form Header Gaskets for SBC Square Port

Graph-Form Premium Header Gaskets for Chevrolet Small Block with Square Port Headers. New Graph-Form exhaust gaskets are extra thick so they conform to warped or pitted header & exhaust system sealing surfaces as much as 1/16? out of tolerance. Proprietary Graph-Form material outperforms all competing brands for high temperature sealing.  Material: SCE Exclusive High Density Super Hi-Temp Graphite; Thickness: .120?. 

Fitment Note: These gaskets require only basic port shape similarity. They seal as well as copper but fitment is easier.
