[Shotimes] rod bearings

What I'm saying is that if the standard size is 'out of spec' with plastigage,
what are the chances that it will be in spec with one of the other sizes? It
would have to be a miracle that the journal wears just the right amount for
the over/under sized bearings to fit. If it wears at all, chances are it won't
wear evenly so you'll have to have the crank turned.
Take of the rod cap, look at the crank journal. If it looks smooth, put the
standard sized one in and don't worry about it.
Once again, if you can't get the clearances right, are you going to pull the
motor to get the crank re-ground?
