Tom,

Really good advice.  They came with an inspection certificate so in theory somebody checked them to ±0.000050".  The certificate shows them to be in spec.

I have a nice, low mileage Starrett 0-1 tenth mike and I'll be able to check everything up to 1".  I'll just have to trust the 2" and 4" blocks but they probably won't get much excercise anyway.
