What is the minimum piston thickness at the valve clearance eyebrow or does someone have a scrap 496HO or Mag piston that I can purchase to see for myself?

I just happen to have 7 spare 496mag HO stock pistons. Wonder how that could be? LOL

I can speak from thousands of dollars of R&D on 496 engines. Don't waist any of your time or money trying to fix the stock hypereutectic cast pistons in 496's for more valve lift. They can accept .510 lift at 12 degrees past top dead center and that's it. Don't try for more it ain't there! Just by a good set of forged pistons and be happy that you got the best for the least!
