Yes, they are usually align-bored in place, its generally the same with cam caps, main caps, etc, the holes in them are specifically matched to the holes in the carrier. Otherwise, the circle created by the carrier/cap might be not prefectly matched up. So you mark them left/right, and up/down. I will put one punch mark on the upper left and two punch marks on the upper right when I do mine.

Talking to someone who's done them before would be undoubtedly helpful. One thing that people do, is make a 2nd set of bearings which have been opened up so they aren't a press fit onto the carrier. THey'll use those to get the shimming right, then switch in the press fit bearings at the end.

If you managed to save your old bearings, they could get used for that purpose.
