Frequently Asked Questions
Do I need new bolts when I install this gasket?
Your factory header bolts will work fine. If they're corroded or stripped, replacement hardware is available separately — but the gasket itself comes solo.
Should I clean the sealing surfaces before install?
Yes. Wipe both the header flange and cylinder head port face with a clean rag to remove old gasket material and carbon. A smooth surface gets a better seal.
What if exhaust leaks persist after install?
Check that header bolts are torqued evenly in a cross pattern. Uneven pressure leaves gaps. If leaking continues, the header flange itself may be warped — test-fit a known good header to confirm.
