TTI 1 7/8 Headers hitting oil pan

I feel your Pain. 1 7/8 headers in an A body biggest mistake of my life. Never Ever Ever will I do that again. Had mine out a couple of times and they have flat spots all over them to make them fit. For TTI to say they fit out of the box is absoloute crap and I installed mine as per the letter of TTI instructions using all there suggested parts.
