Do I need new bolts to install this gasket?

Reuse your factory header bolts if they're in good condition. If they're seized, stripped, or corroded, replacing them during install prevents future headaches. Refer to your service manual for torque specs.

Should I use any sealant with this gasket?

This gasket is designed to seal on its own—no additional sealant needed. Clean the mounting surfaces down to bare metal before install to ensure a tight seal.

How long does this gasket last before it needs replacement?

A properly installed gasket typically handles years of use. Replace it if you see exhaust smoke, smell raw fuel at the header, or hear a hissing leak around the connection point.
