For about a year I've been trying to get this b58 in the car. I kept getting strange readings with the plasticgauge and had get the mic set and dial gauge going. I don't know about this particular engine but the b58 everything is torque to yield so you can't really get anywhere with the factory bolts. Then with the ARP studs the problem I was having was the lube was getting under the cap and not letting things bottom all the way out. I had to mix and match the slightly oversized bearings as I had the crank machined, but I was able to get everything right to 0.0020. Caps 1-4 & 7 started at 0.0025 and then caps five and six were way up to 0.0031. The 0.0026 oversized set just in the upper half, and then in both halves on five and six put everything in spec. On the rod caps I had to use the same oversized set just on the upper half across all six. The rod bolt stretch gauge from summit racing was pretty good. It fit in real nice.
That is interesting about the ARP bolts. Did you stick with them, or swap to BMW bolts? I was going to buy ARP connecting rod bolts because they are cheaper than OEM BMW bolts, but not if they are a struggle.

ARP doesn’t make main bearing cap, or head bolts for the M62 family I think. Only conrod bolts.
