Do I need to clean the header and manifold surfaces before installing this gasket?

Yes. Scrape away old gasket material and carbon buildup from both surfaces with a gasket scraper. A clean, flat surface ensures proper sealing — any debris or residue will cause the new gasket to leak immediately.

What bolts or fasteners do I need for installation?

The header mounting bolts already exist on your engine. This gasket seats between the header and manifold — verify the bolts are in good condition before assembly, and torque them to your vehicle's service manual specification after gasket installation.

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

No. Gaskets are designed for single-use only. Once compressed and exposed to heat cycles, they lose sealing integrity. Always replace with a fresh gasket on reinstall.
