340 Manifolds, Reproduction, Any interest?

I can get great headers right now, they fit like a champ, dont leak and improve flow. They are made in usa out of virgin us steel, 3/8 flange, 16 ga. Only problem, they cost me $600 pr (10-20 pr purchase) and thats after $3500 set up fee so if I sell them at $750 (which is not cheap) I have to sell 24 sets just to break even, that doesnt figure in anything like my time, shipping, the set I made for them to copy, etc. Now if I sell them for $950 that gets investment back in 10 pr, but who will pay $950 for 67-74 headers that work with power steering? I am currently building a set for 64-66 SB but its tough, and very limited market.
I build a block hugger type header for my Jeep swaps and they cost me a **** ton, but they are the best ones out there period. I have to sell them for $460 pr and of course scummit sells a cheap *** copy for $199 that doesnt fit, leaks and is junk but lots of the jeep guys buy theirs instead of mine. I am not a fan of leaky collectors or changing gaskets on headers so I prefer the good ****. If enough others do, then we can move forward but not until i have a general idea that there is real interest.
