At first glance your engine, frame, support and mounts are fine, what you are describing sound like you have a set of one size fit all cheaply made headers.
Get a really big pry bar or piece of wood and bend that collector down slighty after heating it up with a torch-use caution though if you pry to hard to fast you could break the flange at the head where a tube is welded to it or at the collector where all 4 tubes meet it.
My 2 cents
