prechamber from 1979 model in 1982 model?

Hi all,
I have a W123 1982 300D model and I need to replace one of the prechamber due to a brocken glow plug. The chamber is already out and I am waiting for a replacement part sending over from Germany to Australia. Due to the given issues the German DHL does not even send anything off to Australia for the moment but I would like to move my car out of my garage to take care of other things while I am waiting.
I have an old cylinder head which I was able to get rather cheap with all including parts (valves, springs,collar nut and prechambers etc.). Unfortunately the chambers are different (flat on the 79 model) compared to mine (rounded).
I just wonder if I can install the 79 prechamber temporarily until my spare is arriving just to do a couple of things, like also flushing the oil before removing it (need to let the car run for a couple of minutes before I can drain the oil) and other things where the engine needs to run for several minutes.
I am worried if the cylinder gets damaged if I install the flat chamber and would need confirmation.

Anyone can shed some light if this is possible without damaging anything on the engine?

Dang, that's what I was worried about. But thanks for reconfirming.
