You need to perform a compression test. You probably have no compression in those two cylinders. Remove the plugs, check compression, then add about 2 ounces of oil into the spark plug holes and recheck compression. If compression goes up, you have a problem with the rings. If compression does not go up, you have a problem with the valves or head gaskets.
