Positive Stop Rockers????

I have "positive stop" rockers on my 73 302 F100. No adjustment. Just tighten them down.

My lifters (new) are clattering on startup for a few seconds, then they quit. It runs good, but doesnt seem to sound right at an idle (lope) and seems to be choked some while driving. It just doesnt seem to run right.....

Does anyone have any experience or ideas on these rockers? Do they work? Do I need to adjust them like normal hydraulic lifters to get the zero lash effect?

I am thinking I need to loosen them, let the lifters relax, and snug them back up til I get the lash out and then tighten them and lock them?

Any ideas here from someone who has had them or messed with them?

Thanks,<!-- / message --><!-- no sigs except when logged in -->
