Unless I'm missing something, dmsfrr's 90-degree elbows will eliminate your heater and defroster, unless he, too, converted to the mechanical valve, which would be located closer to the firewall, not on the engine.
The open elbow replaces the oem style coolant control valve. Coolant circulates thru the heater core continuously. As opposed to being able to shut it off with the oem style valve or one of the after-market conversion kits.

The heater box in my running car has the heated-air vents closed, but I'm not sure how much heat it's actually keeping out of the car during the summer.
I did buy one of the heater valve conversion kits for the disassembled car, hoping it will be a convenient solution.
