I just got them back from the machine shop and going through them again. I noticed the edges of SOME of the lifters feel like a dull knife edge. Not like hair shaving edge but sharp enough to scrape off some finger nail. They fit in the lifter bores just fine. These are new Johnson HY-LIFT. They may have been fine but I just wanted to make sure. They do look better. The convex seems to be centered better. I have left a message with the machine shop but have not heard back from them but I'm sure I will.
I'm just wondering what proceedures would be used to relieve this edge or maybe its not an issue.
