I have a few of those early rods left from a motor that had them in them and two of them let go at only 5000 rpm on the street!
I had polished them , took a ton of weight off the balancing pad on the big end and the shop that resized them installed ARP bolts also.
I hope you running them in a motor with less then a the 4.21” of a 455 like I ran mine in, other wise I would resell those and get the cheapest new manufactured forged rod and them you’ii be safe from losing a whole short block like I did!
