Overheating Issues, Perplexed

Are you sure your engine builder put the head gasket on the correct direction? FE gaskets can be installed backwards. The engine will run ok but it will overheat quickly.

You should be able to see a little tab on the front of the engine, at the head/block mating point, near the exhaust. If you don't see any gasket there, be suspect

You might want to do some pressure tests on the sytem and cylinders. The video of the car running and coolant puking isn't right. You might have a cylinder leak.

I had similar issues. I have the hole in the t-stat, etc. I fill my system via the heater hose fitting on the top of the intake. Put a piece of hose on a funnel and raise it above the engine and fill until it comes out of the expansion tank. Also if you have a heater make sure it is on and all the air is purged from it also.
