I'm actually more worried about this heater hose fitting, it's so corroded and there isnt a hex head on it from po stripping it out.

Know how to clean out the inside of this dirty corroded intake?

Try heat and vise grips. If that doesn't work you can cut it flush and very carefully with a Dremel (this should be right up your alley) split it in two with out screwing up the threads on the intake.
