How far to rev this 273 commando build

I like to rev them until 1) they stop pulling hard, 2) the valves start to float, or 3) a connecting rod comes loose. In that order. You should let off or shift before 2 or 3 happens, LOL. I wouldn't rev past the cam makers red line.

solid cam ....no valves to float .. still pulling hard at 5900.
