340 cam bearing alignment?

I’d be more worried about the cam spinning in the bearings then then the oil holes off a tad bit. If you were worried you should had not taken the block. I personally go over my stuff before i leave the machine shop. People make mistakes. We used to carve the holes out with a Small pocket knife to get them spot on. Then fit the cam by slightly dragging the knife blade over where the cam was hanging up. Ya did give the machine shop the cam right?!? To test fit it?
