Speedway Motors sells header kits. I got a Ford Sprint kit plus 4 U-shaped tube to split and use to turn the tubes up at the ends to meet the header flanges. I got the flanges from a guy on this Site. You could buy the Roadster kit plus the u-tubes and get the HH flanges. You can get them in stainless or regular. I got regular, because I am going to get them ceramic polished chrome look coated. That will be about $200 for coating. The kit was about $99 on sale about $18 month ago. I did it for a Dodge engine, but Chrysler would be bigger ID. You may want to go to the BB Ford kit or buy a ready built set for a BB Ford, cut off the flanges, add the u-bent ends and your own flanges. These are just some ideas. A guy that is good with a Mig or Tig can lace the parts together and grind them smooth for coating, so you can't see the splices. I have seen some guys use a rolling cutter to cut the tubes. This slightly cups in the end of the tubes and gives a dip at the match spot for welding the tubes together. Then you can grind, sand, etc. to polish the weld smooth, so it looks like the weld never existed. The oh so slight of a dip inside the tube will not be noticeable on performance for a street toy.
Hope this gives you some ideas.

You can find block huggers for 54 - 58 hemis but they may not clear your roadster frame and steering. Check the Header Flange kits that Hot Heads sells listed under Chrysler Parts on the home page of this site. Getting a set of these flange plates and fabing you own headers would probably be the best solution.
