I pulled the magnet & guts out of a monovalve from a P&P yesterday for $5. I forgot to take the spring. Before I replace my existing, I guess I should try to get the air out of the heater core.
Why didn't you just take the whole monovalve and take it apart at home?

If you have a healthy cooling system and engine, air in the heater core should purge itself just from driving with the heat on. The current flow created by the water pump should push the air pockets out of the heater core up to the expansion tank (highest point) and out the pressurized cap.
