the stock rod nuts have been determined to be worse than suspect, they're junk

more than likely you can see fractures in the threads without much 'help'

I think using ARP bolts on a rebuild is a very good idea. I personally change head bolts and rod bolts every rebuild.

Years ago, 1967 ish, Chevy was having problems with the bolts cracking right on the shelf. Brand new.

They would just develop these hairline cracks.

At one time it was recommended to magnaflux the rods as well to pick up otherwise invisible hairline cracks.

All things considered though you need to go by track record and few engine builders report problems with the rod nuts.
