Classic/Antique Car Repair: valve adjustment, ford f 100, feeler gage

Question
I need to know the specs and procedure on adjusting valves for my 64 Ford F-100 with 292 V-8

Answer
The valves are adjusted hot with the engine running to 0.019". it is a messy job as the oil tends to splash. just turn the adjusting screw up or down till the feeler gage takes a little tug to pull it though the gap between the valve stem tip and the rocker arm.
