You'll probably find the wear in a vertical plane, ie very slightly oval/oblong. If so you will have to know how much, and approx how many degrees of the bore is out of spec.
You can save a very slightly worn block by fitting bearings, but once you get over .005 clearance in there, say bye bye to idle oil pressure.
This is exactly why some folks have problems with freshly "rebuilt" engines.
Mic everything.
Keep us posted,
