Rod bolts

OK so I made it thru last season with a basicly stock bottom end (360) and was most worried about the rod bolts as they are the original 100k plus used bolts. I was turning 6k rpm at the end of the straights. I am seriously thinking of installing a set of ARP bolts. I would NOT resize the rods when I do it. I know I should but it wont happen so I guess the question is would I be doing more harm than good if I did this or not.
