Yeah, heater cores are a pain in the ass.
Cyclemut probably has more hands-on experience in this matter, but I've seen my techs tear dashes apart to get to HVAC components. I don't think it's overly complicated, but simply time-consuming on epic levels.
If I were you jrthekid, I'd make damned sure you need to replace the heater core before you have your dash torn apart.
Speaking from experience I can tell you that it's not a very common problem...
What, exactly, are your symptoms?
