Do I need new bolts to install this gasket?

Reuse your existing header bolts if they're in good condition. If they're stripped, rusted, or bent, grab fresh ones—they're cheap insurance against a leaky seal that'll require disassembly again.

Should I apply any sealant before bolting it down?

Gasket alone does the job. No additional sealant or adhesive needed—just clean both surfaces, lay the gasket flat, and torque the bolts evenly. Refer to your vehicle's service manual for the correct torque spec.

What if my header is warped or corroded?

A bad gasket seal often signals a warped header or pitted bolt holes. Inspect the header mating surface and cylinder head for damage before installing. A curved or pitted surface will cause this gasket to blow out the same way.
