Why does engine continue to overheat?

What is your question?

1998 Honda Civic DX Overheating started by blowing hoses and leaking coolant. Replaced thermostat. Radiator and fan working ok. Finally, replaced engine as head gaskets were done in og engine. Still feels like too much pressure in main rad hose and continues to overheat after 10 or so miles; mainly when idling. What could be causing this? Still feels like alot of pressur in some hoses
