Re: break in oils
The last several engines I've built have been solid flat tappet Chevy engines, 2 big blocks and one small block. I used "EDM" lifters in all three as well as Shell Rotella 15W40 oil. On the 2 big blocks, I removed the inner valve springs for cam break-in (the small block had single springs that weren't very aggressive), and all 3 made it through break-in with absolutely no issues whatsoever. I also use moly lube exclusively on all valvetrain components.
