You didn't mention refacing the rockers, or stems, or replacing the shaft.

With those numbers, a certain amount of noise is to be expected.  This is
one of the tradeoffs for 'performance' cams.

With any worn components at all, some variation in measurement is normal,
IMO.  For only .001" or even .002" off, I wouldn't even bother re-adjusting.
Wait to see if it gets worse.

One question would be how you are positioning the cam to check the valve
clearance.  If your reground cam doesn't have the base circle perfectly
concentric, you may get different clearance readings depending on just what
position the cam is turned to.

That should be fine.  Torque should be around 12-14 ft lbs, which isn't
much.  Were they still tight when you readjusted the valves?
