Frequently Asked Questions
Do I need gasket sealer or adhesive with this?
Gasket sealer is optional but recommended for maximum sealing. Clean the manifold and cylinder head surfaces thoroughly before install—any carbon or debris compromises the seal regardless of sealer used.
Will this work as a direct swap for the factory gasket?
Yes. This gasket matches OEM bolt pattern and sealing surface. Remove the old gasket completely, scrape clean, and install new gasket with factory bolts torqued to spec per your vehicle's service manual.
What if I need to reuse the factory header bolts?
Factory bolts work fine—verify they're not stripped or bent before reinstalling. If bolts are damaged, ARP studs are a common upgrade for long-term reliability.
