I did adjust 2 lifters and I have no hood on the truck yet. I may give all a half turn and see how it sounds. Lifters may have a problem but the engine does seem to run ok.
If you say no noise, I have a long way to go.
I am going to the Pumpkin Run today and maybe I can listen to another.

It's pretty common to find them worn concave so it's difficult, if not impossible to get a good adjustment- - - - with solid or hydraulic lifters. Yes, hydraulics should give virtually silent operation, as long as they're in good condition and adjusted correctly.

Listen for ticks or whatever under the valve cover. Others use a dowel or broom handle. You will hear things as there is a lot going on under there.
Another thing I did to get a better handle on any problems was to cut an old inline valve cover so the sides were still there but the top was cut out. I could watch the whole operation with the motor running and not get oil everywhere.
