One thing that will help you get through all of V2 Face files is a python, by Ockham, called FC2Dial.py.   This will allow you to make a whole dial for any V2 expression/face file, and then adjust it's value accordingly!

I could'nt find a link, but am sure it is a freebie, and attached in the link above.  Just save it to your hard disk as FC2dial.py, and not FC2dial.doc.
