Hey Rob, if you get a dull moment and don't mind another favor.... if you drew an imaginary line across the centers of the valve faces, over to the far edge of the intake (right under where your caliper tip is resting), how deep is that valve edge below the head surface? I am just trying to get an estimate on how deep a notch might be needed; gotta keep the notch in the 'meat' of the deck, and above the top ring.
