Some changes were made to the pistons/cam/head starting at engine# d01499 and up. Other than that she stayed pretty much unchanged

Thanks Don ! Did those changes increase the horsepower, torque or any visible differences ?

Nope, Mdae for easier starting with less smoke.. Head casting was also supposed to be less prone to craking

Later D19s had self-canceling spools. Instead of the lever staying the raised or lowered position, they would return to neutral. The valve stack has smaller levers and round knobs, not the rubber handles.
