If you heal, expect to spend the first part of each boss encounter drinking, and praying you do not get interrupted or the party does not need help right now.
My feeling is that, were I a DPS or a tank, I would surely enjoy them much, much more.
As a healer, I don't enjoy them very much. Too much pressure and responsibility. One minor mistake on my part can easily compromise the whole run -- say, drinking on the wrong spot on a boss pull and getting interrupted (or left out of the boss arena), or failing to start drinking in the whole half second which passes from the last trash mob to the boss pull.
Further, as a holy priest I mostly have hard casts, which are hard to do with a continuously advancing party.
Personally, I'd make the time for one chest much longer -- I like hard content, but dislike rushing.
By comparison, heroic raiding is less stressful. Even when mistakes do happen, all your raid lost is ~6 minute time, and you can try again soon. You need to stay very focused, but only during the fights, and you get a short rest after every try.
