Do I need to prep the header and manifold surfaces before installation?

Yes. Clean both surfaces with a wire brush or scraper to remove carbon and old gasket material. A smooth, clean contact surface ensures a proper seal and prevents leaks.

What fasteners do I use to bolt the header to the cylinder head?

Gasket comes alone — you'll need to source or reuse your original bolts. Check your vehicle's service manual for the correct bolt size and torque specs for your specific year and engine.

Can I reuse this gasket if I remove the header later?

No. Gaskets compress permanently during installation and won't seal a second time. Plan on a fresh gasket if you disassemble the header connection.
