Will this gasket come with header bolts or studs?

Gasket only — fasteners are not included. Verify your existing header hardware is in serviceable condition before installation.

Should I clean the mounting surfaces before installing this gasket?

Yes. Scrape away old gasket material and carbon buildup from both the header and manifold surfaces, then wipe clean. A clean, flat seating surface prevents leaks.

Can I reuse this gasket if I remove the header?

No. Once compressed and seated, aluminum gaskets should be replaced with a fresh unit. Reusing them risks exhaust leaks.
