Vvardenfell Visages? Interesting. Does that mod contain some heads from BH?
Yes. Vvardenfell Visages was basically Telesphoros' personal selection of all head/hair mods that were available at the time (and that he had permission to use). Better Heads is mentioned in the readme as one of the sources, though Better Heads in itself is also a collection of works from different artists (some of which released independently before), so it's also possible that there's some overlap because telesphoros and Better Heads used the same source independently.
Btw, I'm trying to add a head pack call World of Faces but its not working. I still get the Vvardenfell Visages heads.
World of Faces was specifically designed to _keep_ many of Bethesda's original heads while adding many new ones. In your game, Bethesda's original heads have been replaced with those from vvardenfell Visages. Since World of Faces leaves many of those alone, you'll still see those. You'll also see lots of VV faces on NPCs that have been added by mods.
