R3W7 Assembly

I made a try with DyKem, it did show a drop in width, down to about .052".

As an aside, I carefully checked valve lift versus lobe lift, etc. There is right at .030" 'lost' between the lobe and the valve. .020" of that is lash, and the other .010" I assume is flex. But, I am using the checking pushrods and they have a small diameter thread, so I would expect some of that .010" to come back once a normal pushrod is in place.
