Frequently Asked Questions
Do these gaskets come with mounting hardware?
Gasket set only — you'll use your existing header bolts and studs to secure them at the cylinder head. Standard hardware that's already in your engine bay.
Do I need to prep or paint these before installation?
Install them as-is. These are gaskets, not panels — no finishing work required. Just clean the mating surfaces on your heads and headers before fitting.
What if the gaskets leak after I install them?
Exhaust leaks usually come from uneven head or header surfaces or undertightened bolts. Inspect both mating surfaces for warping, and torque evenly in a cross pattern. If gaskets fail due to manufacturing defect, reach out with photos of the failure point.
