oh yeah, a roller produces more power on a flatter torque curve. it comes on sooner and lasts longer...

A flat tappet cam is limited to how aggressive it can be because at some point the edge of the lifter will start to cut into the lobe of the cam. A roller doesnt have this problem because the roller simply follows and rolls over the lobe profile. Thus allowing the valve to be opened and closed much faster. Thats where the big advantage is. It is getting the valve open farther and faster then keeping it open longer than a flat tappet cam this is the area under the curve they are talking about.
