Do I need to remove the headers to replace this gasket?

Yes. The gasket sits between the header and cylinder head, so you'll need to unbolt the header flange to access it. It's a straightforward job with basic hand tools and a socket set.

Can I reuse the header bolts, or do I need new ones?

Refer to your vehicle's service manual for torque specs and bolt reuse guidelines. Many shops replace header bolts during gasket work to ensure a solid seal under repeated heat stress.

What prep is needed before installation?

Clean the header flange and cylinder head mating surfaces with a gasket scraper to remove old gasket material and carbon buildup. A clean, flat surface ensures a proper seal.
