Should I change my Main cap bolts??

I am building a 360 and was about to put the oil pan on and thought should I put new main cap bolts on? I priced them from mancini and I have to buy two sets. One set is for the windage tray and the other set is for the rest of the bolts. They are ARP bolts. Its a cost of about 140.00. I already have the old ones in place and torqued down. I have always used the old ones in the past without issue. I want to do this engine right but I could put the 140.00 to use later in the build for something else.
