The only thing I can think of that you need to be concerned with is that you get the bearings aligned properly so the oiling holes align with the holes in the block. I happened to have a cam lyining on my work bench and I just measured the bearing surfaces. The one on the rear is considerably smaller than the front one and all the ones in between are stepped up from the one in the back. This allows you to get the cam all the way in except for that last inch or so with out having to touch any bearing surfaces until it's time to seat the cam. The steps are part of the design and I don't think you need to do any kind of line boring. Racers are continually changing cams with the engine in the car; it would be impossible and impractical for them to have the line bore the engine everytime they swapped out a cam.
