Check out my tutorial on head replacement at http://www.renderosity.com/messages.ez?Form.ShowMessage=1022644 . Be sure to read the whole thread, as I made several corrections further down. Also, the tutorial details how to attach a head to a body, while keeping the BODY's old morphs. If you want to keep the HEAD's morphs instead, check out this thread: http://www.renderosity.com/messages.ez?ForumID=12356&Form.ShowMessage=1163389 . Unfortunately, I don't think it's possible to keep BOTH sets of morphs intact.
