Resizing stock rods? Bad idea?

For what it'll cost to have them resized and ARP bolts installed you can buy a new set of the eagles which come with the ARP bolts for less...i'm running a set in my 30 over 360 with no issues what soever,i also ran a set in my 416 but took them way beyond they're limit and paid the price..500 h.p. max.
