OK. If in fact you determine that a valve job was done and the mechanic failed to verify the hydraulic lifter clearances, you'll have to remove the cylinder head and all the valves, remove the hydraulic lifter body (don't intermix them or the valves), insert the gauge block into the lifter body, put the cam in the down position, and grind the end of the valve stems until the correct clearance is obtained. Just follow the service manual.

If in fact you determine this is the problem, I'd say the "reputable shop, now closed" that did the engine rebuild was not qualified for the job.
