Frequently Asked Questions
Do these bolt directly to factory mounting points?
Yes, these mount at factory rocker points and core supports. No drilling or modification needed — tighten and run.
Will these headers need ceramic coating or paint before install?
Stainless steel doesn't require coating, but polishing or ceramic coating is optional if you want a finished look. Raw stainless will develop a patina over time and is fully functional as-is.
What fasteners or gaskets should I have on hand?
Header bolts, gaskets, and clamps are sold separately. Verify your engine's bolt pattern and core support layout before ordering fasteners — specs vary by displacement and block year.
