HOW ABOUT THE FUEL PUMP ROD, ISNT IT JUST TO THE RIGHT OF DIZZY.
With the stethoscope are you hearing it on the intake itself or below that. Did you insect the lifters when you had it apart?
If possible, run the engine without valve cover and push each of the valve lifters firmly with your thumb, wooden block or equivalent. You should hear a change in the noice or "feel" it when you hit a faulty lifter, spring etc.
