Do I need to prep or clean the mating surfaces before installation?

Yes. Clean both the header flange and manifold surface with a wire brush to remove carbon buildup and old gasket material. A clean, flat surface ensures proper sealing and prevents leaks.

Will this gasket require any special fastening hardware?

You'll use your existing header bolts or studs. Verify bolt condition before install—stripped or corroded fasteners can compromise the seal. Tighten evenly in a cross pattern to factory spec.

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

Once compressed and sealed, aluminum gaskets should be replaced on reinstallation. A fresh gasket ensures consistent pressure and eliminates the risk of leaks from a previously seated surface.
