It just cost me $350

In the thermostat housing at the front of the intake manifold.
A 195 degree should be used.
Yes it will.
The spring goes down into the engine.
Most likely a sticking thermostat.
The outlet from the 350 engine to feed the heater core would be the one closest to the thermostat.
Most came with 195 F. thermostat.
depends on your thermostat, but none of mine ever go over 210

That depends on the thermostat. If it's a 185 thermostat, the engine should run at 185. If it's running too hot, check the thermostat, radiator and water pump. If it's running too cold, replace the thermostat.
The WHOLE engine was BLUE from the factory.
What you're describing sounds a lot like a sticking thermostat. They're cheap, just replace the thermostat and gasket.
Sounds like the thermostat is stuck open. Try a new one.
