curious about valve lash setting/check

Nice catch on the rocker shaft notches, AJ.
I know I can sometimes come off sounding like a plick or a know-it-all; so when I get a kudu, I do appreciate it. I'm just here to help. When I can no longer be of help, I guess I'll retire.
Or maybe I'll just hang around in the N&P and preach scary end-timechit, to those mostly not interested; hah!

Nice contribution , Toolman. that makes it perfectly clear
