Very stubron head gasket

Actually, I do not want to remove the head, just the intake manifold gasket. the intake manifold rests on the heads and there is a gasket between each head and the intake. (I hope in my origional post I didn't say head by mistake) The problem is that the intake gasket was put on using gaskacinch(I belive) I have tried to pound a pry bar between the intake manifold and the head, with no avail. I tried to drive a screwdriver between the head and the intake mainfold and then pry. the head broke off the screwdriver. I am hesitant to pound a prybar between the head and the intake manifold, as I can't replace metal if I gouge it. Once I get the manifold off, I want to replace the gaskets, as the rear gasket is leaking.
