The first time I adjusted my valves. It was obvious the previous owner had the valves adjusted before, because the slot for the rocker arm adjusting screw was reamed out like the guy busted his screwdriver off before he figured out he had to loosen the locknut first. So I replaced them all with cummins part number 3900706 . Instead of the slot for a screwdriver these take a Allen wrench. I suspect there for a 24 valve. Just thought I would share this in case a gorilla adjusted your valves.
