Frequently Asked Questions
Do I need to clean the header and manifold surfaces before installing this gasket?
Yes. Scrape off all old gasket material and carbon buildup from both mating surfaces with a gasket scraper or wire brush. Any debris left behind will prevent a proper seal and cause exhaust leaks.
What hardware do I need to bolt this down?
This gasket assembly does not include fasteners. You'll need the original header bolts from your vehicle — they reuse the same holes. Have them ready before starting the job.
Can I reuse the old bolts or should I replace them?
If your original bolts are in good condition with no visible stripping or corrosion, you can reuse them. If they're bent, rusted, or worn, grab a new set before installation to ensure a tight seal and avoid future leaks.
