Frequently Asked Questions
Do I need new hardware when installing this gasket?
Hardware is not included with this gasket. Reuse your factory header bolts if they're in good condition; replace them if stripped or corroded. Most installs don't require new fasteners, but inspect yours before assembly.
Can I reuse my old gasket?
No. Header gaskets compress under heat and lose their seal after removal. Install fresh every time you pull the header—the cost of a new gasket is cheap insurance against leaks.
Do I need to prep or prime this gasket before install?
Gaskets ship ready to install. Clean both the header and cylinder head mating surfaces with a gasket scraper before seating the new gasket—remove all old material and dirt to ensure a tight seal.
