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?

Crap like that I usually sand blast, then use an aircraft fluid resistant epoxy primer to recoat. You may be able to find a shop that can heat that fitting cherry red and remove it for you.
