Advice on attaching metahumans head to another body

Thank you for your response. I beat my head against the wall and that I just didn’t try, but MetaHumans can’t unload from Autodesk Maya to UE4. MetaHumans turns out to be broken.
When in Autodesk Maya the character MetaHumans correct, the head MetaHumans correct, the hierarchy is correct. But once we take the MetaHumans file from Autodesk Maya and try to insert it into the UE4, it doesn’t work.
Did you find concrete steps, a phased solution? Thank you brother.
