I have purchased the auto compression release cam for my WR426 and while installing it I noticed that the lobes are quite a bit narrower. Is this how it is suppose to be? I remember reading that the lobes are different in the lift area but I don't remeber anything about the width. Can anyone confirm this for me before i button this thing up and hurt something. I need to get larger valve shims today so iwill not be puting it together until tonight.
