I use model scale 0.11. Works great. Sometimes you may have to raise/lower head after sizing. Not sure where this came from but i have this doc with it:
Copying Heads for NWN
By Martigan
Basic Information:
OVERRIDE vs. HAK
If you only want to be able to use the heads for NPCs, then a hak is fine. If you want the players to be able to select the heads at character creation, they will need to place them in the override directory as well as being included in the hak.
FINDING THE HEADS:
You can find the head models and export them from NWN Explorer.
The heads can be found in the following locations:
Original Campaign: NWN Main Data --> data\\models_02.bif
SoU: NWN:SoU Main Data --> data\\xp1_models.bif --> Models
HotU: NWN:HotU Main Data --> data\\xp2_models.bif --> Models
CEP: NWN HAK Files --> cepanatomy.hak --> Models
-AND-
CEP Update: NWN HAK Files --> cep1patch.hak --> Models
When you change the name of a model (whether it is an animal, a placeable, or a head) you will need to go into the *.mdl file and change all the internal references also. The easiest way to do this is to open a text editor, and do a replace, finding all the old names (which will match the original file name without the .mdl extension), and changing them into the new name (which should be the name you gave them, again leaving off the .mdl extension).
There is also a reference to the texture (coloring of the various parts) in the mdl file. The easiest way is to just copy that file as well, and rename it to match the new mdl file name. This does, however, increase the size of your hak or override file that others will have to download. The way to bypass this is to look through the file for "bmp", and when you see that followed by the .mdl name, make sure it points to the original texture name.
SIZING THE HEADS
If you are just taking a stock head, (or one you downloaded off the vault) and are making it useable for other races, you will also need to resize it. Halfling-sized heads look really funny on half-orcs. The program I used for resizing is Merlin Avery's, and is available either on the vault, or on his web page (all links are listed below)
Female Labels SCALE Male Labels SCALE
Halfling pfa0_head*** 0.65 pma0_head*** 0.7
Dwarf pfd0_head*** 0.95 pmd0_head*** 1.15
Elf pfe0_head*** 0.8 pme0_head*** 0.85
Gnome pfg0_head*** 0.82 pmg0_head*** 0.9
Human pfh0_head*** 0.85 pmh0_head*** 1.05
Half Orc pfo0_head*** 1.2 pmo0_head*** 1.2
Half Elves use the human heads. For the large phenotype (aka fat), replace the 0 with a 2 (female halfling would be pfa2_head***). If you don't do this, the head won't show up when people choose the large bodies. When changing heads from one race to another, you'll have to use a calculator to determine the actual numbers for changing the sizes. You can't just take the base model for a human head and increase the size 120% to make a half orc head, you need to figure out the actual difference for these. (All the numbers listed here are percentage of "normal" size, as listed in Bioware's appearances.2da for helmet sizing.)

I didn't come up with most of this information myself. I researched it, and found answers from what others had done, and looked through the NWN .2da files. Thanks to the following creators:
