Built a 468 for my buddies 68 Camaro. When we took the dual plane of and put a single plane on it, you could hear the lifter noise thru the bottom of the intake since there was only a thin piece of aluminum covering the lifter galley. I would go 1.4 turn.
How do you adjust them? With it running or off? I always do my hydralics with it running.

just stabing at this but what about cam lobe flatten on the lobe you lost the lifter and pushrod on?adjust them all again and run car then go back and check and see if the lifter that you replaced is loose again.maybe the cam lobe is flatten on you.something to look at.
