OK everyone I may be able to make another header here very soon. Any offers? Just so you know they are made of schedual 40 mild steel TIG welded and in a log style. I will chanfer the flanges as much as possible to give the best flow I can with my design. It will be painted with a high temp paint that does flake off but the ceramic in teh paint adherse to the metal and does not flake. Let me knwo i'm looking at 300 a header.
