If you want to open another can of worms, there is a debate on what part of the lift curve sees the most stress, hence valvetrain deflection. A clue: it's NOT at full lift where spring forces are highest! Max velocity is about mid-lift; max acceleration is just off the seat where the valve starts to open most quickly
