I shimmed a pair of stock rollers solid then shimmed under the pedestal to get zero lash. This also told me what the preload on the lifter would be. It' a tad light at .048 and .043. Hughes says .080 on these lifters so longer pushrods may be needed.
And yes, I had all the plugs out so I could feel it better.
Wow, removed lifters and shimmed, removed rockers and shimmed, etc.
I would have driven to work and back to get the dial indicator. The time spent taking the motor apart and putting it back to together correctly is worth considering.
That said, you are close and should be OK, just don't float the valves with RPM.
