Solid Cam, Use it or Not

Ok guys I finally got around to getting the lifter pics. Theses are the only ones that have wear. All of them have the circles from rotation. The fourth pic that looks like it has wear on the left side is the lighting. I snapped to try and show the wear pattern of circles. With the exception of the other three all on the drivers side they all look good. I have not held the bottoms up to a lifter side to see if I can see any light around the edges.
Thanks FABO

A side picture with a straight edge on the top of the lifter would show a crown or a dish. That would be the only way to see their condition in a picture, Are they crowned or are they dished or are they flat. They should be crowned
