What headers will fit???

The engine mounts from schumacher I used are the #A83L. Needed those because my 73 dart came stock with a 318 and a spool mount K member, the QA1 K frame is made for up to 72 production with the donut style mounts. The engine mounts are correct for this application, considering K frame and situation. UPDATE: today i measured engine position, height is correct but I did find the passenger side is off by approx 7/16" possibly bent frame rail. I loosened the K frame and shifted it as far over as I could manage. Also was able to shim the engine mounts and the gear box. With these changes and the header cleared the gear box finally when setting back down on the engine mounts in the K frame. very close tolerance, too close for my liking. So from here I am going to semi flatten a 1/2" section of the header and shaved down the gear box where it is almost touching to hopefully give me a little under 1/4" of clearance, the undercarriage with the torsion bar clearance is very simple now. Thankfully it is looking like the TTI's are going to work at the end. Keep you guys updated and I put up a couple pics. Thank you for all the input!
