Mike V: Good question. I just assumed .003 was removed from both sides.
If you remove .003 from one side and none from the other the cap will be angled to the low side, and somewhere across that circle of the journal there will be .002 clearance. There will be more clearance to the cap on the high side and less on the low side. The mathematicians and engineers here would know more about the effects and geometry than me.
Personally, I mic the shims and if off on either side by more than around .0005 or so I sand them down so the shims are pretty much equal thickness. I use some 400 grit and a flat surface. On the teardown that is going on now for the new Burlington crank I am using Timesaver to lap in the babbitt, and like the results.
