??? you cannot adjust valves unless you have adjustable rockers and most Mopars don't--have them. So do you ? "have adjustable rockers?"
The next thing is, if you were able to adjust them without getting the valve gear all "out of shape" EG the adjuster clear to one extreme or t' toher, then you are done, unless there is some damage, bent pushrod, abnormal wear on pushrod, rocker, came, etc
If you do not have adjustable rockers, then the only way to make up slack is longer pushrods, but you really need to find out WHY. Is the cam wearing? you have a burned valve? etc?
