It is all about making the valvetrain stable at the rpm you mentioned, you are correct, not every combo can run up there and make power, but some can


Nascar...... .875 dia, flat tappet, 60 mm 9000+ all day long with almost 0 valvetrain breakage


Most stockers have "square" lobe cams.....think about that for awhile


Edit....the rulebook specifies "lift" as far as I am concerned that is all they should be checking, weather its at the valve and/or at the cam
