Cm2350 combustion in cooling system

[Petegraintrain]

yes the head was replaced with a new one. I told the mechanic that did it that I wanted an oem cummins head but i never saw any paperwork so for all I know it could he a cheap Chinese one. Has 391 gears with 24.5 tires so at highway speed (105 kmh) i sit at 1500 rpm. And I never let it pull hard under 1400. Preferably keep it above 1500 when pulling hard. Also forgot to mention that the coolant passage is routed correctly to the back of the block. But yea once I have the adapter I will send you my file.
