bronze lifter bushings

Well my 3 year old camshaft looked just fine after being in my 150,000+ mile 30 year old 318 block which never had anything I believe done to the lifter bores. I was taking it the hone was just a quick clean up in case a burr was in a few bores. Lifters need to rotate in the bores.

Wounder if they just over did one lifter bore?
