The valve will dictate where the normal final rocker position is. Certainly you would Have noticed if one valve was 3/8" taller than the rest.

Now look to see if there is a 1/4" difference in how much adjuster sticks out BELOW the rocker. That will tell you is something is seriously amiss.

A 1/4" is not a slight mis adjustment in a rocker. It won't be the source of a slight valve train noise. Either the intake valve won't close and the car runs like total crap, or the push rod falls out, the car runs like crap, and your oil pressure goes to zero because the lifter usually gets launched out the bore.

Take a close look at your stuff, then report back.
