Do it this way... Make sure the cam gear is pointing at the notch in the head. Turn the head upside down and stablize it with blocks of wood (or whatever you have). Then, pour some solvent, or the used oil ON top on the valves. After you have done that, look into the holes where the carb and the exhaust bolt to. If the fluid you poured onto the valves is in there then one or both of the valves are not sealing correctly and need replacing. In the one pic you posted the exhaust valve doesn't appear to be seating. Looked like there was some space between it and the valve seat.
ohh there is space. put it upto the light. (looked in the exhaust hole) and you can see right out the valve
