If the shop knurled the original iron valve guides to on the cheap somewhat restore the needed guide clearance, then with that amount of exh valve stem clearance the exh valves will need positive seals also.
Problem is the head will need to come off again to cut the guide tops.
This assumes that the exh valves did get the needed O-ring stem seal in the retainer.
Maybe since positive seals where used on the intakes the head was assembled without these O-rings on the exh valves, but the head gasket sets do come with the needed 12 O-rings, I know that for sure.
