"Intellect, spirit and mana restore all serve the same purpose: bigger mana pool.
Intellect gives you loads more right here and now, but zero extra regen. The shorter the fight, the better intellect is.
Spirit is annoying, because even though it potentially gives you loads of regen, casting disables it (or most of it, if you have meditation).
Finally mana restore gives you regen you can count on, that works at full speed even if you're casting loads.
1 int (with mental str 5/5):
1 minute fight: 16.5 mana
5 minute fight: 16.5 mana
10 minute fight: 16.5 mana
1 spi (with meditation 5/5, assuming 50% full regen time)
1 minute fight: 4.3 mana
5 minute fight: 21.6 mana
10 minute fight: 43 mana
1 restore
1 minute fight: 12 mana
5 minute fight: 60 mana
10 minute fight: 120 mana
Various fight lengths according to MUSE stats from my screenshots:
Kazzak, ~3 minutes
Hakkar, ~10 minutes
Gehenas, ~2.5 minutes
Sulfuron, ~3 minutes
Golemagg, ~4 minutes
Majordomo, ~5 minutes
Ragnaros, ~7 minutes
Broodlord, ~5 minutes
So for each item I'd try to weigh it up and figure out how much mana you think it'll give you for your average boss fight.
I usually go by "how much mana will this item give for a 5 minute fight with 50% full regen time", then consider secondary stats as well. Mana restore tends to win out in each slot.
Personally I'm not much of a fan of +healing in raids. It's definitely awesome for 5-man (both for healing faster and saving mana). But with multiple healers in big raids? the bigger your heals are, the more you're going to overheal.
In my current gear, my stats are roughly:
6100 unbuffed mana (yep, quite low)
300 unbuffed spirit (ok)
99 mana restored every 5 seconds (w00tage)
And ehrm I guess there's a bit of +healing on a few of my items, but definitely not much.
I'll be the first to admit it's very onesided and I'd probably be better off for going for some more all-round stats, but I *do* like to specialize
Edit: fixed stats for spi. "

before a MC boss fight I would drink nightfin soup (mana regen buff food) - nowadays there is also sagefish recipes, mana oil for weapons (doesnt overwrite an enchant) and Buxton can do th mana regen on bracer enchant - this post is for info/consideration only ofc - up to you how u play/spec/handle your class
