Frequently Asked Questions
Do these gaskets need to be installed dry or with sealant?
Install dry for best results. Header gaskets rely on crush fit at the port face — applying gasket sealer can actually prevent proper sealing and cause leaks. Tighten fasteners in a star pattern to ensure even compression across all ports.
Can I reuse my old header bolts?
Inspect them first. If they show corrosion, stretch marks, or thread damage, replace them. New fasteners ensure consistent clamp load and prevent gasket creep. Old bolts can relax over heat cycles and cause exhaust leaks.
What if my headers are warped or pitted?
Warped or damaged port surfaces won't seal properly even with new gaskets. Have your headers checked on a flat plate or resurfaced if needed. A bad seal at the header face creates exhaust leaks that no gasket can fix.
