I find the discussion irrelevant. I have a fair amount of experience with engines in the 900+ hp range that use store bought, box stock rocker arms. They hold lash, don't break, and run just fine for multiple seasons. So that covers about 99.5% of what anyone on this board is doing. There might be only one or two guys on this forum who run 1000+ hp stuff that require something special. Guys with 500, 600, or 700 hp engines don't need to move the shafts or machine the stands. All they need to do is buy a quality set of rocker arms and install them correctly.
