No, "head" is a verb in this case. Related to "heading" (i.e. what direction a vehicle is pointed at while moving), I think, rather than the body part. I can't find the etymology beyond words meaning the body part or "primary"/"main". There's no direct equivalent in German for example despite the shared etymology for the other meanings. I would guess that it is related to the body part in a figurative sense in the same was as "face" (i.e. turn your body in a specific direction) though I have no idea how "put your head there" would come to me "go there". I wonder if this was before or after "heading" became a thing for ships (which generally move in the direction they "face", so the "heading", i.e. how the "nose" is aligned, could go on to become a verb). EDIT: I'm not sure it's pars pro toto because I'm not sure it directly refers to the "head" in the sense of the body part rather than the "heading" which is not directly related to the actual body part when talking about vehicles like ships.
