Ah, so include Terror's script above as well as appearwithheadshot.fpi for the appear. Also, set headshot=x to headshot=55. It'll decrease the range of the headshot to mostly the head and not from the upper chest to the head.
If your using Fenix Mod, you might also want to include "removehead" in there for a nice effect, so it should look like this:
:always,shotinhead=1:sound=x,removehead,suspend,coloff
I haven't checked the manual, but I'm pretty sure I remember "removehead" being the command.
