Amsterdam to Rome layover of 85 minutes, will I make it to the gate? (Delta)

I have 1hr 15 minutes from gate to gate and I do not know which terminal or gates I am landing in and taking off from. I presume this information will be available the day of travel. AMS looks like a massive airport which I would like to familiarize my self in case I have to run it.

Also, do you have to go through customs during an international layover?

Is it likely I could miss my flight with these factors?


Arriving in AMS at 6:00 AM

Taking off to FCO at 7:15 AM
