Roller Rocker geometry questions
This pic should help clarify the effect of valve tip height vs rocker arm height. If the pattern is on the intake side of center you raise the shaft.If the wear pattern is on the ex side of center you lower the shaft (which us mopar guys cant do) so we use a lash cap. In the case of the OP's situation the Crane rockers are likely a bit longer than they should be (as Raymond noted) causing the scrub pattern to be out toward the exhaust side. In reality it probably would never give you any issues running the way it is, but I'd rather make it as good as I could within reason.
