Breaking in a Used Engine

Breaking in a Used Engine
Is there any procedure for "breaking in" a used engine? I'm about to swap in a used engine with about 80-90k km on it and the dealer is telling me I should break it in. I've tried searching and couldn't find any thread/post about breaking in a used engine. I've also thought about it logically and it just doesn't make too much sense to me. I would have imagined if an engine has been sitting for an extended amount of time outside of a vehicle, it would be the same as storing a car for winter or an extended period of time, and thus the start-up procedure should be relatively similar no?
The dealer is going to do the following (which I know has to be done):
-Install the engine
-put in appropriate fluids
-run the car for 30 minutes
-change the oil
They are telling me that after they have done all this, I will need to change the oil again within 5 days, and again after another 2 days.
Is this overkill? Or should I just follow what they say?

wtf ?,. there is no requirement to break-in a used engine, the majority of break-in occurs with in the first 100 miles so it is long past break-in.
I would only change the oil as suggested if the engine was assembled prior to installation , but if the engine was put in as a complete unit I see no reason to do it. One new oil change is sufficient and don't pay them for any extras. They're giving you a line of b.s. IMO.

None of what the dealership says is necessary to maintain my warranty. I think I will go with the advice given to me in this thread. I'll make sure the dealership does that first oil change since I have a couple friends that work at the dealership my car is in currently. I'll then followup with my own oil change after I get the car back and put in some 10W-30 AMS oil.
Thanks for the help!

Your dealer is stupid
break-in was finished a long time ago. Check the oil when you get the car back (for some reason everyone thinks they know how to check the oil in this car, yet I keep getting engine jobs by people who swear the oil level was good)

People who work at dealers know absolutely nothing.
