I will look at that this evening after I get home from work. Lifters were near perfect and sold already. I don't recall any grooves..Weber is very picky and said it was reusable but showed a little ware on lobes, but I had already decided to go stroker and different cam selection, otherwise I would have reused it.
It's written on the box..slight roller tracks was the ware.comes with thrust button also
