So i got a new heater core, perfect match.... did not take a pick before taking out the old one.. does it matter which way the hoses hook up ? or a way to tell which hose is the return.

I know this is a simple process and i screwed up..

I actually just called them to verify the proper way to install their low idle wye. I asked about heat exchanger flow direction for you. Flow direction does not matter. So just hook your hoses up. It’ll work as it did before.
