Okay, I found the post from Pseron Wyrd, it gave no instructions (only what he did with them after he cloned them). I left a question to him on that thread.
On that same thread was these instructions by SubRosa, but they are for Skyrim:

There's also a way you can use the Character Creation (showracemenu) to export faces for NPC creation.
Just adjust the sliders like normal and get the type of face you want. When you're done, open the console and type SPF <insert a name here>. The saved SPF file will default into your game's root folder (C:\Program Files (x86)\Steam\Steamapps\Common\Skyrim) Open the CK and go to the Character Gen Parts tab and click the "Import" button. Now you have an NPC with the desired face that you want in the game.
I've made a lot of unique looking NPC's and followers using this method.
Would this work on Oblivion too?
