Try applying the head as a morph target.  From the Face Room, click the "Spawn Morph Target" button. In the Pose room, the head, left eye, and right eye will then have morphs labelled "Head1", "LeftEye1" and "RightEye1" that you can adjust as needed. When each is set to 1, you'll get the same head shape you got in the face room (providing you start from the default Alyson face shape).

Then if you created a face texture, you can also use the "Apply Texture Only" button in the Face Room to apply the texture you created in the face room.
