Frequently Asked Questions
Do I need new fasteners to reinstall the headers?
Bolts and studs are not included with this gasket set. Reuse your existing hardware if it's in good condition, or pick up a hardware kit separately. Most people grab new bolts while they're in there anyway.
Should I clean the manifold surface before installing these gaskets?
Yes. Wipe both the manifold and cylinder head sealing surfaces clean with a wire brush or gasket scraper to remove old gasket material and carbon. A clean surface ensures a proper seal and longer gasket life.
What if I get an exhaust leak after installation?
Start by checking your bolt torque — exhaust fasteners can loosen under heat. If bolts are tight and you still hear a leak, the gasket may not be seating properly due to warped surfaces. Most leaks trace back to surface prep or uneven bolt pressure rather than the gasket itself.
