Do I need new bolts or hardware to install this?

You'll need the header mounting bolts from your vehicle. Refer to your service manual for proper torque specs. Don't reuse old bolts if they're corroded or stripped — grab new ones while you're at it.

Can I reuse my original header bolts?

Not recommended. Header bolts see extreme heat cycling and often seize or lose clamping force. Fresh hardware ensures proper seal and easier removal next time.

What prep is needed before installation?

Clean both the header flange and cylinder head mating surfaces with a gasket scraper to remove old material and buildup. A clean surface is essential for a leak-free seal.
