Dave,
Probably the greater advantage of the "roller tip" is it should reduce
friction at the contact point of the valve. This should reduce the valve
side load and increase the life of the valve guide. This can be especially
helpful in high lift cams or cams that have a fast ramp.
The reduced friction also likely reduces some power loss and decreases
heat. To what extent that is beneficial verses the cost is likely up for
debate.
