Dave you do not need to take the valve out. I do not think it is your problem but to make sure just remove the manifolds and put some air pressure in the #2 cylinder. Spray soapy water in the ports at the valves and see if you get bubbles. I have not tried that but it seems like it might work. I think as some experts have said you have a warped head or the head gasket is not sealing for some other reason. You need a machinist straight edged, not just a flat piece of steel to properly check it. Just my opinion.
