What headers will fit???

Ok so an update on this issue. Monday I got the TTI shorty small block headers, with the header pipe adapters. I was trying to upload image, not letting me saying files too large. Anyways the drivers side is hitting the side of gear box. Specifically the #2 tube, is hitting, and I still have another 1/4 inch to lower the engine mount down to tighten it fully. I don't see any way the adapter pipe is going to sit onto the flange. Seriously don't understand why I am having all these issues. Wish I could upload a bunch of pics for you guys to help. 1973 Dodge Dart Swinger stock 318 setup, I swapped to QA1 K frame which is older style donut mounts. Got the proper schumacher engine conversion mounts to go the 360 block, stock gear box, flaming river steering column. The only thing I am coming up with is that I have the schumacher mounts sitting all the way at the bottom position for lowest engine position into k frame , i did these to prevent the distributor from hitting the windshield wiper motor. so if i can life the motor slightly by shimming the mounts? Or maybe the engine is not centered perfectly, supposed to be 16 1/8th inch to center of crankshaft according to schumacher and firmfeel.
