My Answer is based on clues, symptoms and info in your question. Please include everything. Thanks
if your hoses are hot to and from heater core i would not think its a clogged heater core.
Are they both hot?
Please advise your definition of "Hot," I'm saying the Two hoses located underneath the hood reads 165 & 172. The two hoses have a upside shape. How can I validate the flow to the Heater core, which I believe is located underneath the dashboard.
Is the a valve, at fire wall.
