'Cause I'm an Arcane Mage (main spec, OS is Frost) I use Arcane Blast on Bosses, but just use Arcane Barrage and Arcane Missiles (if it procs) on trash mobs. And I have 3 heirlooms too (head, chest and cloak), but alas, the int from those isn't enough.

Anyone have any tips?

(never had this problem with my 85 Balance Druid, ever)
Two things come to mind - Evocation and Mage Armor. Also, are you using Mana Gems? If you're a Blood Elf you've also got Arcane Torrent every two minutes. Lastly, make food and eat it, every time you're not in combat, even if you don't get the full benefit. Even a few seconds of eating will regen a pretty decent chunk of mana for you.
