I appreciate your input. I've got all the books but the help here makes a big difference. I enjoy taking time doing the measuring.
I was only considering 0.005, not 0.050. Just enough to even them up with minimal effect on balance or compression.
The block was supposed to be squared. I don't know if 0.005 off is common?
The 440 I just got back from my lmachinist was worse, .010" variance lowest to highest between all four corners. I gave him the rotating assembly for mock-up before any cutting was done, all nice and flat now.
