Pull the valve cover. If any of the lifters seem to be out further than normal, or if any of the rockers are loose you have bent valves on that cylinder.
But again, if you have obscenely low compression on any cylinder chances are you have at least one bent valve. If even one valve is not sealing properly, it will result in "0" compression for that cylinder. While rebuilding a buddy's 1G a while ago, he had two cracked exhaust valve guides on cylinder 1 which resulted in "0" compression....the valves were not even bent.
