Don’t beat yourself up. Looking back at your pictures and seeing that roller lifter damaged. I now think the lifter went away, I doubt over reving had anything to do with it. Even though it says Lunati it’s made by Morel. Both have know issues. Didn’t see the damage on other roller lifter on the adjacent lobe. Which is no fault of engine builder. A good explanation, when the cam on base circle and moving up the ramp that lifter wants to turn the tie bar prevents that from happening. My guess is it started to bind and took out the lifter, so could be a combination of both weak lifter bore and lifter going bad. It’s hard to diagnose from those pictures but I’d like to see picture of the adjacent lifter. If your up to it. I’m guessing it’s the luck of the draw on weather or not you get a good set.
