Problems with the 6.4 Powerstroke; Coolant blows off

Hello Stanley!
Thanks for your answer!
I also thought, that the head gaskets are blown.
But I did a CO2-Test on the coolant bottle/degasbottle. And there is no CO2 in it.
If the head gaskets are blown the high pressure in the coolant system comes from exhaust gases, that are pressed into the coolant system. Exhaust gases are CO2 - so CO2 should be in the system if the hg are blown.
When I coldstart the engine and let it run on idle for a couple of minutes (I tested up to 20Minutes) there is no pressure in the system - everything works fine up to ~190℉.
But if the temperature reaches ~195℉ there is high pressure on the system.
Don't knowing what the problem is, I drive the truck for ~7000mls with this symptoms. I think with blown head gaskets the engine should have gone the long way to nirvana...
Or do I have completely wrong thoughts?
Thanks for your answer!

Hello everyone!
You guys helped me so much, I have to give you an update.
I checked my thermostats and deleted them. Without the thermostats I drove for some km and there was the same problem.
Because of the high pressure in the system my radiator starts leaking.
Now my truck is in the shop. I ordered some new Viktor Reinz head gaskets, A.R.P. head studs, mishimoto radiator, updated upper hose and new thermostats.
I hope my truck will work fine after repair.
Do you think I have to update anything else?
Greetings Philipp

Pretty much what you did, HGs, studs, water pump, thermostats, EGR block off. (I elected the block instead of removal in case I wanted to trade or sell the truck it would be an easy reverse). I also got the updated rad hoses and coolant tank. i had it done at Bill Hewitts powerstroke INC. I happen to live not far from there. On edit: I already had the delete and tuner and had the tranny built in 2012. So I was looking forward to many many miles (had 75K on when I did it) of trouble free towing when I got hit.

so look at the drivers side wheel well. At an angle you can see into the side of the radiator. See if you can see any evidence of a leak there.
Also it might be a good idea to replace the degas bottle cap. A $5 dollar part but then eventually do not hold the pressure like they should. 16 lbs of pressure is what you should be seeing.
Any white smoke or sweet smelling exhaust?

looked in there a few times havnt noticed anything special. also have went through 3 caps just cause its cheap and common with no help. theres is a few puffs of white smoke upon a very cold start like in the 10-20 degrees and goes away quick. I don't notice and sweet smelling exhaust. and I sure love the smell of diesel fuel!
