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.
