Art,
What is the actual Rocker Ratio? You know,measured... Measure the lobe lift and then the valve lift @ "0" lash. Then divide the required lash, at the valve tip, by the RR and set at the roller.
You do realize with a set up like that you can alter the RR with tip length of the valve. It can also move the cam timing around a little.
