You are forgetting the two who can heal the most. A second place goes to Nasus with 6 Warmogs + health masteries + health/level runes and a Q farmed enough to make his passive life steal heal him from 1 life to full life (which would also be a one hit Nashor, I think...) when using Q.

First place goes to Sion, with the unsatisfying answer: unlimited. And he only needs one Atma's Impaler from it. His E gives him infinite health, which means Atma's Impaler gives him infinite attack damage, which means his R gives him infinite life steal with one hit.

But let's calculate Nasus' maximum. There are no teammates needed, because there are no health aura's (or am I mistaken?), and his maximum life stolen is his maximum life - 1.

6 Warmogs fully farmed give him 6*1270=7620 bonus health. His base health on level 18 with ult activated is 2630. 2630+7620=10250. His innate life steal is 20% on level 18, which means he has to deal (10250-1)*5 damage to his target (as said just above, "overkill" damage also gives you life). 10249*5=51245 damage. This means that he needs 17006 stacks on his Q: 51245-110 (base damage) = 51135, 51135-116.3 (base AD) = 51018 (rounded down). 51018/3=17006
