I thought of that but due to the different radius of the follower the information would be meaningless. I would close the lifter down either with lash cap or washers behind the lash adjuster. I generally set cams working with opening and closing events and that might be warranted here not knowing just how asymmetric the lobes are. Going by centerline will allow that both cams will be the same but might be a degree or two from the book numbers.
