These pict, are taken from drivers side of block, I tried marking the cam on the two worst lobes, may be hard to see, the lobe marked with red is almost non existent, the one in front of it marked in white is in pretty rough shape as well.

The first cylinder in the front and the 3rd cyl back are marked minor damage.

Definitely a set pattern where contact was made on all of the pistons, I dont know enough to say what thats all about.
