It's a very simple check. Just find a weak spring to install on one intake and one exhaust, just enough tension to keep things in their proper relationship, and adjust the lash to zero like we discussed. Then roll the engine over by hand and check how close the retainer comes to the top of the valve guide. If one cylinder is OK, the rest of them should be also. The pictures you posted look like the retainers are getting awfully close to the guide tops!
