From your picture it looks like the engine is running around 180, which is about right. When the engine is hot, feel the 2 hoses going to the heater core, they should be almost the same temp as the hoses going to the radiator. If the heater core hoses reemain cool, it indicates that either the heater core is clogged or the restrictor in one of the heater hoses is clogged. If both hoses are hot, then there is a problem with one or more air doors in HVAC plenum or the temp control is messed up.

see if any of this helps. most times a flush of the core with the garden hose will do it.

That's where mine temp sets with a 160 thermo and fans programmed to turn on at 180. I remember with it stock it would set around 200-220, so I don't think it's stock even with the heater on.
