I agree on the rule of replacing the rod bolts, but if the rods had pistons on them and no obvious signs of hard treatment or damage, then a simple magnaflux crack test on them would be more economical than buying a new set. After they checked out fine there, if he wanted an even better set of rods than maybe even when they left the factory, he could send them to a place in Michigan called Monkey Wrench Racing who have a cryo facility and will do the rods for $75 or less. Read up on the cryo process for the still little-known process of metal stress relieving and metal grain re-aligning.
IMO, even with big name brands like Eagle and SCAT, they are still made in china - still made to a price and seem to be closely aligned with PCE (ProComp Electronics) who seem to make an identical rod under their own name for about 80% lower price.
