Are your pushrods maybe a touch too short?

That is a good point, were all the rocker clearances checked? Rocker to retainer, rocker to stud etc?
The pozilock screw seems to "out" too much, indicating pushrod length too short.

That could be the case, but if that happens the valve stem in the guide should still be intact.
In the photo, it looks like the valvestem must be bent at the top of the guide.
