Max Lobe Ramp For Solid Flat

Man....
as the ramp speed goes up the valve closes harder,you better have a very good
valve train..
Flat tappet cams with 165 to 170 @200 should keep your hands full and wallet empty for a while...no need for a 1" lifter you can get yourself in more than enough trouble with the stock diam lifter. just my two cents..I've been there done that.
