Can anyone help me out/offer some advice?

Wanting to remove the head off an energon barricade, well one of the figures used for that mold anyway.
Thing i need help with is removing his head. is there a way to do it without destroying the head? if so how?
if not whats the best way to get it off. and how would i go about attaching a new head in its place?
spent a few days searching and cant find an answer anywhere. thanks in advance.
