Here's mine.... IF the head is made of Plasticene as you say - the clay already has oil in it. In my experience of using oil clay (plasticene) I have never needed anything else to release the plaster from the model. Nothing. In fact, if you put vaseline on the plasticene, I'm thinking that anything you put into the mold to make the head will pick up a coating of the vaseline which may be a problem when it somes to painting the head... Couple of hints.... Plaster expands a bit on setting. So pulling it off the model will take a bit of effort. Try not to have too many undercuts in your model. Some details can be put in later. Good Luck.
