Find out. Set up samples with what you've got with specified 
key height, dip, and blow, leaving the back rail alone for the 
moment. See if you can get sharps and naturals to work the 
same with the official numbers. If you can't get the naturals 
to full dip without burying the sharps, you'll need to either 
shim the sharps up as suggested, or replace the naturals to 
the correct height relationship with the sharps.

This was discussed in the long distant past of nine days ago 
on list.
