Differences with EGR and nonEGR engines

I am rather new to the SC world and I still have to ask questions. I am currently rewoking a Black '89 SC and found the Heads to be toast. I then came upon another '89 with a good running motor but popped real good in the rear. The question is what are the differences between a motor with EGR and one without EGR???? I have yet to understand why the nonEGR exhaust mount holes seem to measure 1.53mm different from the exhaust mounts on the EGR exhaust.?????????:confused:
