nice job, few comments questions...

i dont think our systems are self bleeding? you didnt mention anything about that...
what about the water now trapped in the block & heater core that will be mixed with the 50/50 coolant?

I remember on my 5.0L there was a coolant drain on the block, im sure our engines have one as well (although im not familair with the 4.0 as i am the 5.0 that was in my old truck)
