To answer some of the questions.....

This cam was not getting reused anyway. The motor will be a new combo including new cam and lifters. I sold the heads and will not bother to measure the spring pressure. I have the spring pressure written down somewhere, but can't find it right now.

I don't remember if it is the same on the up and down or not - would have to look when I get home. One lifter had a scored roller biu other than that they looked fine to me.

The pictures don't do it justice. Some of the grooving is quite deep - more than just a light catch with a fingernail. I might try to measure it in the lathe with an indicator. I would not feel good about reusing this cam. My buddy called it a "tomato stake".

Knowing what I know today I don't like my choice of oil either. I believe that I was skidding the rollers on the cam because of one or more variable's. I think it may be a combination of oil and maybe spring pressure.

My biggest thing is to make sure that the new motor cam does not experience any issues..............
