Frequently Asked Questions
Do I need any additional gaskets or seals beyond what's in this set?
This is a complete header gasket set — it covers all the gaskets needed for header installation. If you're also replacing manifold gaskets or other exhaust components, those are separate items.
Should I use any sealant or adhesive with these gaskets?
Header gaskets are designed to seal under clamp pressure alone. Do not use gasket sealer or adhesive unless your service manual specifically calls for it — it can prevent proper seating and cause leaks.
What do I need to know about surface prep before installation?
Both the header flange and block surface must be clean and flat. Wipe away carbon and old gasket material with a scraper, then clean with a solvent rag. A smooth, dry surface ensures a proper seal.
