Help! 7.3 idi troubles

I've got a '93 f350 4x4 7.3idi with injector problems. It was parked over the summer with bad clutch, after remain injectors installed.(<1500 on install). Get it back Wednesday drive maybe 100 miles, starts popping like exhaust leak,but no joy. Pop hood, its coming out factory airfilter.
This is with full fill up, no additives. Now I'm low on go juice, fill up + stp injector treatment.
Please, any suggestions?

I've pulled valve covers, while running. 1 rocker was moving 1/8-1/4" less than others. Pulling lifters Friday & will inspect pushrods at same time.
Possibility of of popping back on power stroke?

If that's not all that's causing your problem, it is certainly suspicious This engine doesn't have a high-lift cam to start with.

I hope you haven't wiped a cam lobe. If lucky, just a lifter collapsed or gummed up.

Any suggestions on reloading new lifters?
