I worked in an engine shop that did lots and lots of Late Model Stock engines ( all solid flat tappet ) . We used all cast iron cores and tooled steel lifters. We always broke in engines without the inner springs and used break in oil. I don't remember hardly ever seeing any issues.Our lifters were not coated at all.
I'm just wondering how the tooled steel cam would do with non coated tooled steel lifters. I won't likely own a set of Shubeck lifters. I had an engine builder put a set of Shubeck lifters in a 340 once and we never made a pass. The ceramic came off and it literally destroyed the cylinder walls and pistons. It was around 2000 I think....so 25 years ago.
