I would pick 1or 2 but any of them would be fine in that engine. It will he the last thing to fail unless you overheat it.
Transmission is the biggest weak point, 1991 was the worst year (first year of electronic transmission). When I was a kid my parents had a 1990. It got wrote off at 150k miles or so but it only needed an alternator and blower motor in all of that time. It was a very reliable car. Except it didn't like starting in cold cold weather. The 1979 Impala with a badly adjusted choke had to come to the rescue a few times when that happened.
