Yes, they are centered. There only off-centered axially for the lifter rotation. It would also require different ramps on each side of the lobe if you'd want the valve action to be 'symmetrical'.

Btw1, you say: "like toward the rotation slightly to make the stress of lifting the lifter more in line with the movement they want it to make" but its just the opposite: The more mushroom effect > the larger discrepancy between lobe shape and valve action (the further the red and blue lines im my figures will be apart). Moving the lifter TOWARDS the rotation would yield in more mushroom effect in the opening side, and less on the closing side.

Btw2, you only need very slightly larger lifters to maintain the full mushroom effect, so the KG lifters will do the job perfectly. (I figured they might still not be wide enough, but they are)
