Fresh engine, wiped cam? Tick? (new pics added)

your factory rocker arms are always less than spec and never identical, it seems, so your actual lift at the valve will be lower than the cam spec says...but just a little.

when you turn the engine over with the rockers bolted on, look at your springs at max lift....you need to be sure your springs are not binding or that the reatainer isnt hitting the valve seal/guide. If they (the valve guides) were not milled down a little from stock height, they also may be your problem.
