The shank should be just short of parallel to the strings when the
hammer is against same.  If the hammers are so short that the shank is
vertical or past then you have a performance problem as well as a
regulation problem.

You can put a small bubble level on a square block os wood, check the
strings with the bubble then check the hammer shank.  Simple but
necessary.  

If the hammer bore is longer then you will have less after touch then
you would like.

You can tell nothing about the length of the tail on an upright.
