file export, wavefront object, single frame, uncheck universe, check v4 head, uncheck all options except as morph target, save as carmel head .obj.

Open new v4, select head body part, click properties tab, load morph target, carmel head, under morphs for head body part dial carmel head to 1. Depending on if the original head morph had corresponding eye and neck morphs results may vary.

Another option, save head as pose with morphs option. Load fresh v4 with whatever morph package that you used to create carmel, apply pose to head.
