Mine ran 21psi making 245@ the fly for over 2 years with standard rods/arp rod bolts. As long as they're mapped well they're ok, when the engine finally let go a few months back it turned out to be a shattered piston skirt and not a rod as i had thought so proves it can be done. I've just put steel rods/forged pistons in the new engine and if you really want peace of mind i'd try and stretch to these if you can. My rev limit was 6.5k and used to spend a lot of its time there lol.
