Frequently Asked Questions
Do I need new hardware to install this gasket?
You'll reuse your existing header bolts and studs. If any fasteners are damaged or stripped, replace them before seating the new gasket to ensure proper clamping pressure.
Should I prep the header and engine surfaces before installation?
Yes—clean both mating surfaces down to bare metal with a gasket scraper or wire brush. Any old gasket material or carbon buildup will compromise the seal. Let surfaces dry completely before fitting the new gasket.
Can I reuse this gasket if I pull the header off again later?
Once compressed between the header and engine block, aluminum gaskets lose their sealing ability. Plan on replacing it each time you remove the header to avoid exhaust leaks.
