        Ummm.  Now I really have a question.  Since the factory NEVER 
     EVER can make each rocker the same, AND since you can maximize 
     your lift when you rbuild by buying the appropriate tolerance 
     rocker, you may be able to adjust the lift more or less 
     accordingly.  About a year or so ago, Petersons 4WOR did an 
     article on this very practice, and you can get sometimes up to 10 
     HP by maximizing the lift with the factory spec rockers used at 
     the limit.
     
        Are you SURE that the numbers are valve lift, not lobe height. 
      That would also mean that the cam grinders, KNOW the factory 
     specs of each brand/model of rocker.  Aftermarket rockers are 
     also available to chenge the ratio, so what gives?
