According to this post and a few others in the Dreadsylvania thread in GD, if you use certain items against the bosses you get a harder version of the boss plus extra loot.
It would be nice if Mafia checked for the equipped items in the Boss' Non Combat and suggested equipping it (or gave a link to equip it). So far only 2 items are known, as suggested by the mentioned post above
