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.
