I agree to pull it to break the engine free. This will also allow for the clutch not being stuck too. If that doesn't turn it then start soaking the cylinders and valves with Kroil or another brand you like. Let that sit for several days and try it again. Do this until it breaks the rings loose. Also pull the valve cover and makes sure the valves are free and working. After several attempts at this if it is still froze then you may as well pull the pan and start taking it apart.
