Face Texture Oreo?

[fiction4life]

I am working on a custom race for us within a custom spell mod. The spell uses a simple script to turn the player into my custom race for a limited amount of time e.g. werewolves. When I cast the spell, the torso, hands, and feet switch perfectly but instead of switching the head from the player race to my custom races's head the game engine renders both sandwiched over eachother. The end result is two faces clipping through one another (and also rather terrifying). Can anyone help me solve this issue?

Tinkering with this mod has solved the double face problem, but I have still been unable to acheive a full race transformation. No matter what I try, the player character's head remains the original race. The rest of the body switches as scripted. e.g. A Nord head on a WoodElf body. Could somebody PLEASE point me in the right direction?

 

Thanks in advance.
