Had the valves adjusted on 12/19 seemed to make a difference. Started the truck Saturday morning and it seemed fine. Drove three blocks and herd the loudest poping noise ever. The truck seemed to drive fine with the exception of the M60 going of under the hood. Had the truck put on a flatbed and brought back to the place the serviced it. ANY IDEA'S? I'M FRAKING OUT. STUCK VALVE IS MY GUESS.

Could be a stuck valve or even a broken rocker lever. Pop the valve cover off and have a look for anything obvious.

I'm guessing the valve adjustment may have not been done properly.. not to belabor the obvious.

Maybe the lock nut was not tighten enough ?
Are you a regular at this shop / know them ?
You may want to see for your self , before letting them have access , just to double check .

Nut backed of the exhast valve. They fixed and drove throught out the day to make sure it stayed tight.
