Anyone interested in all stainless headers for SBC? We are looking into offering these. Would be 1.5" primaries with 3" X 7" collector and 3/8" thick SS flanges. Complete SS construction no mild steel, no rust. Raw mill finish with MIG and TIG welded construction. Anyone interested let me know. I need about a dozen or so committed buyers to pull the trigger on this. Or target price on these is around $300. No other derby header builder offers all stainless construction.
