Frequently Asked Questions
Do I need new hardware to install this gasket?
Hardware is not included with this gasket. Check your existing header bolts before installation—if they're corroded, stripped, or damaged, grab a fresh stainless steel header bolt kit to ensure a proper seal.
Will this gasket seal properly without any prep or adhesive?
Clean both the cylinder head and header surfaces with a wire brush or gasket scraper to remove carbon and old gasket material. The fresh contact surfaces and the gasket itself are all you need—no adhesive required. Torque fasteners evenly in a star pattern for even clamping.
What if exhaust still leaks after I install this?
Check for warped header mounting surfaces, cracked castings on the header itself, or undertorqued bolts. If the header or cylinder head is damaged, sealing the gasket won't stop leaks. Inspect both surfaces under a straightedge before committing to this gasket.
