I had to reasearch it online and found it to be.007" on the intake and.011" on the exhaust. Check the clearance of all the rockers arms, tappets, first to see if this is close to the setting just to make sure. There is very little information on the engine. You might benefit greatly from getting a Haynes Manual for the engine/truck.
