If it's rusted trying to force it without a penetrant might break it. I had an old Ford and freed the thing up using penetrating oil and no problems afterward.

When the car has dual exhaust and a stuck open or missing riser, I used to stick a rag in one side and let the car warm up that way. Drive a few miles and take the rag out.
