Do I need to clean the header and head surface before installing this gasket?

Yes. Scrape away old gasket material and carbon buildup with a gasket scraper or brass brush. A clean, flat surface ensures a proper seal and prevents leaks.

What hardware do I need to bolt the header back down?

This gasket comes alone—you'll need the header bolts and washers from your OEM fastener kit or sourced separately. Check your service manual for bolt size and torque specs.

Can I reuse the old gasket, or do I have to buy a new one?

Replace it. Exhaust gaskets compress permanently under heat and won't seal again once removed. A new gasket costs less than chasing an exhaust leak.
