I don't know if this is common knowledge yet, but I figured I'd share since I haven't seen this mentioned or addressed in any of the race change guides (that I could find).
I've been very impressed with the female draenei model since it was released (more than miffed that horde got stuck with anorexic elves :yuck: ) so I spent a good deal of time tweaking my F.Orc --> F.Draenei mod and getting something I was satisfied with.
However, for the longest time, I've been stuck with a marked lack of horn...
But no longer! RAWR!!!!!
Here's how it goes [To do this, you'll need some sort of DBC editor, just as you need something like photoshop to modify textures.]:
Draenei horn data is stored in the same place as earrings and facial hair (this is how I stumbled across this fix in the first place). However, on races without horns (I've only tested orcs and blood elves so far) the geosets that reference the horn models are turned off...so we have to turn them on.
The file you need to extract is stored in:
Data\enUS\locale-enUS.MPQ
and in that mpq:
DBFilesClient\CharacterFacialHairStyles.dbc <---that's the file you're looking for
It looks something like this:

Using the hair style info, find the race/gender of your character and using something like ModelViewer, find the facial feature you're using (the "Style" Column). Facial Features for female characters are most often piercings, but they probably also apply to things like tusks and tattoos as well.
The "Geoset100" column is what you need to modify. Since there are 7 f.draenei horn styles, putting any number 1-7 in that column should turn on the horns...ridding your character of those painful holes in her head forever.
Save the .dbc file and repack it into a "patch-enUS-#.MPQ" (don't use # 2 since blizz is already using it) with the proper tree path, put that back into the enUS folder and you're done.
I'm not the best at explaining these things, so if you have questions feel free to ask.
