The wire is between the valve and seat, so it is not fully closed, thats where the compression is going.
with the engine off, and the VC off, and the heel of the cam on the follower of that valve, you will find it is a bit looser than the rest, along with the retainer down a tad more.
no need to pull the cams, just pop the follower off, push the spring down with a long hefty screwdriver a bit and the follower will pop right out.
But at this point the head has to come off.
Once the head is off, then a better inspection of the pistons can be done.
EDIT
If that is the fire ring, then not only are you loosing compression out the valve, but across the HG to the adjoining cylinder.
