Stock Rocker arms clearances and fit

Guys,
I can't believe all this feedback! THX. A few comments:
1) I will check for shims under the shaft. (I had someone helping me when we removed the shafts last year, but I can't recall for sure if shims were in-place.)
2) Car does have a "mild" cam but not sure of exact grind.
3) When cold, there is definitely NO PRE-LOAD on any of the valves/push-rods. Some have more gaps/play than others and I will measure them all cold to get details.
4) Also plan to check operation at idle. (How much oil splashing should I expect at idle? Do I need to rig a shield to keep oil fm running down onto headers?)
5) I do not recall exact push-rod length from when I removed them last year. I simply compared them all to each other and their length was consistent; tips looked nearly new.

--I will provide feedback in the next day or 2 on my progress.
THX
