I isolated it by using the stethoscope and confirmed it by taking the lower valve cover off and going right to the valve. I can move the valve stem side to side probably a mm in each direction. The valve guide has less than 10k on it too. In addition, in my discussions about this issue with Neil Harvey at Performance Developments, he said he has had examples of this happening - loose guides making tapping noises.

When I have the motor out, I'll look around some more, but I feel pretty good this is the problem.
