I definitely would not consider exorcists anti horde at all, regardless of taking 3 (which I would certainly take 3 in my army as well). Also when you say flamers and heavy bolters are you talking about your 3 immolators, I don't see either anywhere else (except maybe 1 of the 2 on the chimaera too)? If so 3-4 is not really a lot either, especially since you can't snap shot with flamers (so if you move your immo/chimaera w/heavy flamer more than 6 inches, no shooting for you.)
Personally I'd be running flamers on either the sister squads, or the henchmen crew, or both. Having a good mix of melta/flamer I have found to work best. If you go melta heavy (like it seems) vs armies that rely on cover saves (Orks, IG, DE, etc) you are losing a ton of potential kills. That AP1 is nullified by that ADL wall or the ruin they are hiding in.
If you are banking on your exorcists to kill hordes and you have 2 bad turns (d6 shots can be awful when your dice say no) you are going to be in a world of hurt when they get to you. Sure, if you have bad rolls with other units its going to be hard as well, but it only takes 3 bad rolls for your exorcists to do next to nothing (when you roll that d6 shots). If you have a unit of 4 heavy bolters (not that I like retributors very much) you have to roll 12 bad rolls. Not to mention that 12 shots are from 1 unit, vs 3 tanks that are fairly close in point costs on a 1 tank to 1 ret squad basis.
Sorry if I seem overly negative, I am just trying to relay what I have seen from the games I have played.
