Also, lift does not play as big of a factor on the required spring strength as duration does. The more duration you have the steeper the cam lobe will be and the more succeptable to floating it is.
Not entirely true. The lobe geometry is affected by the total lift in relation to the duration. The higher the lift, the further the valvetrain has to move. The shorter the duration, the less time the valvetrain has to move the distance set by the lift.
