You have asked a rather large question, which is more likely to fit in the Newbies' posts.
First off, do you mean you wish to import a 3d head from another program like DAZ? Something like that would be better accomplished in DAZ itself.
Second, are you going to animate this face, or just use it as a static model? Animating visemes is my specialty, and it takes a fair amount of training to do it well.
Third, what is your goal application? Is it a video editor? Or a game? Those are two very different goals.
