Chevrolet Big Block 396/402/427/454/507/572 Header Stainless Steel
Stainless steel headers built for serious big-block power. Designed to flow exhaust efficiently across the full displacement range from 396 to 572 cubic inches. Corrosion-resistant construction holds up to heat cycles and road salt without degrading.
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.
