[Question] Trouble with Helm Fix

[PhyrreFly]

After scrounging around on here, I have a semi-working helm-fix for my tauren to draenei swap ... but its still a little off. The hat shows up right, but the poor gal's hair sticks through it. I was wondering if anyone could clue me in on how to get it to work right? So far I've just renamed all the files in ITEM > ObjectComponents > HEAD from DrF to TaF ... so I'm missing something, but I can't figure out what. =(
Thanks y'all, and apologies in advance for the newb question.
