The extremely high exhaust temps modified engines produce make it tough for a conventional gasket to survive. XX Carbon gaskets are made of 100% carbon-felt material embossed on a steel core; there’s nothing to burn out. This material withstands long term exposure to over 2000°F; this makes for a long-life gasket! The XX Carbon line of gaskets offers superior sealing ability even on the worst flange surfaces.
