Perhaps there are missing dependencies in the makefiles.  Try to
remove the relevant PFB files to force a run of fontforge.  This
should automatically build the OTF files also.

It's not explicitly specified.  Horizontally, it is determined by the
metric box of the flag.  Vertically, the flag's stem always has the
height of a multiple of the space between two staff lines.  To be more
precise, if the flag's glyph name is uN or dN, the flag stem length is
N-2 staff line spaces.

BTW, I put the following into a small shell script to get `proof'
images of the font (here at the design size 20):

  mf '\mode:=proof; input feta-noteheads20'
  gftodvi feta-noteheads20.2602gf \
  && mv feta-noteheads20.dvi feta-noteheads20.proof.dvi

The resulting DVI file can then be viewed with, say, xdvi.
