Does the cam/rollers look good?

Are any of the valves sitting high in their seat?

What is the detent clearance after setting the engine brake rocker correctly?

I am thinking that there is more to it that someone just hasn't caught, or perhaps something that is not being done correctly?

It could be running hot in only one cylinder,.. has anyone checked the thermal difference of the cylinders?

Has anyone pulled the intake manifold off and inspected it for soot packing? -- Maybe it is getting starved of air? or a blockage in the exhaust manifold?

Intake manifold is good because i did the egr tuneup new doser new sensors
