Frequently Asked Questions
Do I need to clean the header and head surface before installing this?
Yes. Use a gasket scraper to remove all old gasket material and carbon buildup from both mounting surfaces. A clean, flat surface ensures a proper seal and prevents exhaust leaks.
Will I need new bolts or studs to install this gasket?
Check your factory studs for corrosion or damage before reusing them. If studs are intact, you can reuse them. If they're seized, stripped, or heavily corroded, new studs or bolts rated for exhaust heat are recommended.
Can I reuse this gasket if I remove the header again?
No. Once compressed, aluminum gaskets cannot be reseated reliably. Plan to replace it each time you pull the header to avoid exhaust leaks.
