looks like a single piece PC chamber design in the J series D3400 engines.
Drain coolant!
Get the set screws out,
get the correct adapter tool to fit down the chamber (hex?).
Remove injector lines and injectors. You will need a socket for that purpose. One can be made up from the correct sized 3/4" drive 12 pt socket cut in two and extended with pipe, trimmed out for the injector nipple to allow it to make enough of a turn to move the retaining nut at least 1/12th of a turn each time.
If the head's off, spray the thread area with penetrating lube or heat chamber and melt candle wax into the thread area before allowing it to cool.
If not off, you just will have to have a go with a big pull handle and cheater or an impact wrench sometimes will rattle them out better, I would break them loose and then turn back in and repeat after every round to avoid as much as possible taking the threads out of the head. there are helicoil kits available to repair the thread if you do damage them badly.
