Hydr lifters, adjustable roller rocker arms, had some noise, tried to adjust preload did i mess up?

I know personally I’ve had trouble with hydraulic lifters and adjustable rockers.
I only know of one guy who adjust them by feel. He said some lifters being hydraulic bleed down slower or faster than others. Same set of 16 and all respond differently. Personally I stopped using that combo and run adjustable with mechanical lifters only- again way too much work for such little gain.
