He's got a 350 chevy which likely has hydraulic lifters, so no feeler gauge.
I almost always tighten to the rocker nut until the pushrod doesnt spin, then go 1/4 - -1/2 turn more. you have to do with like a normal valve adjust, so it has to be in the right spot: TDC 1 or rotated 360 degrees.
Since yours was a running motor, thats about all you need to do, if you put a new cam and lifters in I would remove the valve covers, and tighten down when running, until the clacking goes away, then 1/4 turn more.
