another overheating problem

The reason I pulled the head is after changing the head gasket and replacing all the other gaskets and valve seals I had white smoke shooting out the exhaust and it became harder to start. I took it as ring blow by at first. But I also noticed coolant leaking down the side of the block right after. After retorquing the head the leak off the block seemed to stop but I still had other issues which as I stated I thought was just ring blow by.
But with coolant levels still going down little by little then it over heating I figured it must be a warped head or faulty head gasket or improper installation. The only thing I had not replaced was the radiator. When using first got the car the heater core was leaking so I changed it. Then I replaced all the hoses, and radiator cap. When i yanked the head the first time I changed the tstat.
I tried running with no tstat but that still made it over heat if not faster. I've replaced the cap a few times as well. Boiled the tstat and all opened and closed.
The head shouldn't have any blockage as I soaked it it parts cleaner and shot my water hose through it thoroughly. I had high water pressure at my old house and all gunk SHOULD have blown out if there was any. I really do think it was improper gasket install.
I'll call the machine shops tomorrow and see about getting the head pressure checked.Hopefully my boss finally pays me. About to start hunting for new work lol
How do you check combustion in coolant lol you shouldn't have combustion in coolant
And the old radiator I'm not putting back in. I'll 've taking the one from the van sealing it off and adding air to it to see if it leaks. The radiator could very well be part of the problem as well. But I don't remember billowing smoke out the exhaust before the first gasket change.
The only thing I didn't do before I tore the head off was a compression test. The radiator blew on me while driving and I was out of town and had to repair it on the side of the road about an hour and half from home. Since I'm already working on it, even if it wasn't the head causing the over heating I had been leaking a bit of oil still and would rather change the head gasket to be sure. I'm just taking preventative measure not just throwing time and labor and money at it. My lady drives it and I'd rather spend the little extra then have a bigger problem later. Any time I personally drive it, it's longer drives. It doesn't over heat on her as she only drives it 10 minutes to work and 10 back but she is switching jobs to an hour drive as well so for me better safe than sorry.
Now I'm just rambling, dampened alcohol. I'm gonna check my neighbor tomorrow as well to see if he has a precision straight edge I can use. Anyways I'll post back my findings. Thanks for all the input
