If there no compression, you have to have valves stuck open. Have you removed the valve cover to check?

either the timing has jumped, the valves are stuck open, or you have holes in the tops of 3 pistons. As far as fixing valves that are stuck open, it really is based on the cause. Are you certain the timing is correct and with the valve cover off, you don't see any sticking valves?

I agree. I feel that is what happened. Let me know what you find when you remove the head.
