Hey all

Is it normal for my newly rebuilt stock specs 235 6 cyl daily driver’s lifters to tick for 30 seconds after overnight sitting?

Once they pump up the tick goes away.

Wondering if something needs done...adjust, replace, etc?

The noise you are hearing is in the valve train. You probably have valve improperly adjusted. With a cold engine, remove the valve cover. Get a two foot piece of garden hose to use as a stethoscope.
Have someone start the car and using the hose, identify the noisy rocker. Adjust the valve per manufacturer recommendation. For a temporary fix, you can try Motor Honey. Motor Honey works by improving oil viscosity. Motor Honey coats engine parts as well as quiets noisy engines.

If he ticking goes away after 30 seconds, I would leave the valves alone. With the engine stopped, any lifters which are under open valves will leak down. That's what is causing the ticking noise when you start the engine. The lifters fill back up once they get oil pressure and then the ticking stops.

Don't know what oil you are using but perhaps a higher viscosity may help.
