I figured out how to do it (I had to re-export the head from poser, modify in Hex, load back in poser as a morph target, save CR2 then use this LINK to create a PZ2 from it)  I guess thats why the utilities to do this are not cheap, lol!  I used the info from JJroland above, thank you!

Thanks all for the help.  It worked, but I did it so quick, my Hex job was more like a Hack job, so I'll need to work on that some more to smooth it out.
