If you are checking it with hydraulic lifters the plungers are bottomed out when you tighten down the lock-nuts unless you shimmed them up internally. This means the pushrods are too long, not too short. I'd subtract .050" from the measurement and order them at 9.200". This will allow you do adjust the rocker arms down so the plungers are .around .050" from bottoming out in the lifters which isn't a bad place to be........
