Default Turbo H2B cooling system issues

Having an issue with the cooling system on my turbo H2B car. There are continuous air bubbles when bleeding the system.
When letting the car bleed with the radiator cap off every once in awhile a lot of coolant will shoot out of the top of the radiator. I have let it bleed a few times for at least 30 mins now.

When shutting the car off, with the radiator cap off the coolant will make a gurgling sound inside the radiator. Sounds like it's still bubbling.


Car gets hot around 210 degrees when sitting still. Gets over 220 degrees really quickly when driving it so I shut off.
I've replaced the radiator with an aluminum dual core, new thermostat, new radiator cap. I'm thinking it's either the water pump or the headgasket at this point.

Any help is appreciated. Car is finished now but the cooling system is giving me a hard time!
