Ravana many heads defined!
Brahma granted him these boons in addition to his 10 severed heads and great strength by way of knowledge of divine weapons and magic. Thus ravana known as 'Dasamukha' (Dasa = ten, mukha =face).
Here is a painting with 3 heads coming out
For molding reasons all three heads can be detached at a later stage, when sculpting I have to always keep in mind the molding process and the undercuts and difficult areas that would cause a problem later. Hence the arms and legs will also be removable!
