Hey Pete . . . that "CrankaTalk" app of yours is really working well!

Thanks guys for the detailed explanation - it is something that folks new to flatheads and the associated valvetrain just don't learn or even know about these days.

These grind/weld adjustment methods were what all factory engines and major rebuilders used back in the day. "Adjustable" lifters were an aftermarket item that cost extra money, added a lot of weight and sometimes had issues with the adjusters backing off and then having to be readjusted. But, Johnson adjustable lifters enabled many a backyard enthusiast to easily install a new cam in their engine - using normal hand tools. I'm sure "adjustables" have helped sell a LOT of flathead cams over the years!
