For the thermostat with the one way valve, just take a fitting thermostat into the parts store and tell them you want a cap for X temperature, they usually let me in the back to inspect the caps.
Find one that is dimensionally the same and the correct temp.
There are MANY suitable thermostats that will work.
My recent one had the thermostat element offset from the center. No harm as it doesnt interfere with anything.
To "burp" the system without the special thermo you run the engine up to temp and when the thermo starts to open a bunch of bubbles will come up and the fluid level will drop. You just fill it to proper level and that should be the end of it.
It does help to park the car on an incline so the air bubbles want to rise to the front of the head where the thermo housing is.
This lets gravity do most of the work.
To "burp" with the special valve, park on an incline, (engine off) make sure the cap is in place and squeeze and release the upper rad hose a bunch of times. This will release the air beneath the thermostat up into the radiator.
Run the engine up to temp and be sure the fluid level is correct after cooling.
