Possible bad lifter
The only one that I paused at was the 2nd from the bottom in the group of 4 in the bottom pix. The wear pattern is grey all across instead of shiney in one area.
Check each lobe peak and look for any sort of a slight break in the smoothness of the lobe. The pix below shows the type of thing to looks for; this lobe is at the end of its life. When things wear further, the little flat area shown by the arrow will extend across the lobe.
