Thoughts/do I need to dent my new headers, new pics ?

I took a couple more pictures for explanation. It is for all sake and purposes, a 73 and up big bolt pattern disc brake front end with a 68 to 72 V8 K member with Schumacher motor mounts the motor measures up to be in the right spot ( slightly higher now because of the shims ) I am going to track down some other Pittman arms for comparison I think .
