I had mine milled .045 and the only.bolt that didn't line up perfectly was the support from the alternator bracket to the front of the head

Damn, well hopefully .030 off won't have that issue. I can't wait! I have a BONE STOCK 5.3 coming out for this h/c LS1 to replace. I'm ready for this 200rwhp bump lol.
