A kit to improve coolant flow - no more dead-ending at the rear of the block!

I'm sure you guys saw my headgasket thread. Here is a bit more on the coolant flow-through kit for the 5.9L block:

It is my understanding that on the larger trucks equipped with the 5.9L Cummins, a coolant line is connected at the back of the block (where a freeze plug is placed on Ram pickups) that runs back to the radiator, making the cooling system a flow-through system rather than dead-ending at the back of the motor, therefore keeping the rear cylinders cooler. I plan on buying the kit from Cummins and installing it while I have it torn apart.

Not sure if this would be for people running mild mods.. but may be an option for higher HP guys.

Here are the parts Cummins lists for the kit.
