the wear pattern on the lobes look fine. Remember the lobe is tapered--higher on one side than the other, and the lifter faces are slightly crowned, so the lifter acually rides on one side of the lobe (the high side) not the center.

The marks on the sides of the lifter look pretty normal, its not uncommon to get some 'burnishing' almost a scratching, but you shouldn't actually see grooves or any serious scratches (hard to tell from your pics)
