sbc valve adjustment problem

hey everyone i adjusted the valves on my 383 and it seemed like it wasnt running to it full potential so i took the valve covers off and went back through my valves this time i it did with the engine running and it seems like when you run down the 5 and 7 valves the engine runs poorly and if you loosen um to where the engine picks back up there loose i have adjusted valves on engines plenty of times but these things are driving me crazy the engine is a 383 scat crank,eagle forged rods,speed pro dish pistons,282 comp cam,single plane high rise intake,750 holley carb 305 heads that have been hawged out if anyone could give me some advice that would be great thanks.

When the rocker is "loose" is it clacking? if not it`s okay.
If it is clacking then try this. Get the engine up to temp, pull the valve cover, back off the rocker,, slowly,, until it starts to clack, then slowly tighten it until the clack stops then slowly give it a quarter turn. Give it a second as the lifter may need a minute to reset itself. I always adjust with the engine running, this way I can hear the effects, plus I can do the old trick of zero lashing hydraulic lifters. You have a nice combo, but I couldn`t see spending that much money to choke it down with 305 heads.
