Ugh no doubt, I had to hammer the center 2 tubes of my driver side Hedman Tight Tubes shorties so there was enough clearance with the bottom of the head for the headers to seal. F%&#in annoying, took me a bit to figure that out because they were also hitting one of the mounting bosses on my Magnum block (the ones that are used for the modern truck mounts)... got to a point where I kept grinding and hammering but they still wouldn't fit till I looked a bit higher, "Ah-HAH, you dirty SOB!" lol
I wonder if the Trick Flows are better in that regard...
EDIT: Also just remembered off the top of my head, I definitely have a longer alternator belt on my setup because once I pull the alternator up to tighten the belt the hold-down bolt is pretty much all the way at the end of the swing-arm bracket.
