anyone not think that either the Lunati or Howard are going to be easier on your valvetrain than the "pushing the envelope" chevy grinds while providing more area as indicated by the .200 durations?

Help me understand something here.... I think that last sentence says that that aggressive Chevy grinds are going to be harder on the valvetrain. Have I read that right? But the .200 duration is smaller for the aggressive Chevy grind. So is the problem up between the .200" lift point and the peak lift?
