Do I need new header bolts when I install this gasket?

Reuse your existing bolts if they're not stripped or corroded. If bolts spin freely or won't hold torque, source a replacement set before installation. Tighten to your vehicle's service manual spec.

Should I apply any sealant to this gasket before bolting it down?

This gasket is designed to seal dry — no additional sealant needed. Clean both the header flange and cylinder head surfaces with a wire brush to remove old gasket material and carbon buildup for the best seal.

What's the return window if this doesn't fit my application?

Check the fitment compatibility on the product page before purchase. Once installed, the gasket cannot be reused. If you have fitment questions before buying, reach out to customer service with your vehicle details.
