Why would you use other than the TFMs you already have?
The Type 1 versions of the fonts supposedly have identical
metrics to the MetaFont/PK versions.

A dangerous situation when the DVI processor sees different 
TFM files than TeX.  Which is why I prefer DVI processors 
that do not need to refer to TFM files (after all, the font
knows its metrics).

Run TFtoPL on the TFM files and compare.

Generally checksum mismatches provide only something between
zero and one bit of information.  Which is pretty poor for a
32 bit field (:-)
