Do I need to scrape off the old gasket before installing this one?

Yes. Clean the header and cylinder head mating surfaces with a gasket scraper or wire brush to remove all old material and debris. A clean surface ensures a proper seal and prevents leaks.

Will this gasket work with my current header setup?

This gasket is cut for standard V8 exhaust ports. If you're running aftermarket headers with non-standard port sizing or spacing, test-fit before final installation to confirm alignment.

What do I need to reinstall the header after gasket replacement?

You'll need the original header bolts and fasteners. Refer to your vehicle's service manual for torque specifications. Some builders use a light high-temp sealant around the gasket perimeter for added insurance, but it's not required.
