Missed on this combo?
Good detective work on the valve lift, Mike. I think you have found part of the problem. Move your indicator right down onto the top of the lifter as close as you can get, (as YR said) and see if your get the full lobe lift spec; that will settle that issue.
And note again that Bullet looks to spec the valve lift by simply multiplying the lobe lift times the rocker ratio, so once the Mopar system lash and geometry errors are into the picture, then it will never get to that advertised lift, even with true 1.6 rockers.
