Can't get low-speed temps down.

Pulled the stat and put in a genuine 180 stat. Flushed all the coolant out. Running with water and purple ice - no coolant.
Before
idle - 210 to 215
1500 rpms - 210 to 224
2000+ rpms. - 204 to 212
After
idle - 194
1500 rpms - 183 to 188
2000+ rpms - 179 to 183
Fixing the exhaust leaks tomorrow!

My cooling system had about 30K miles on it along with a Turner 4.6 engine. Started to fluctuate temps and climbed really high once and noticed the plastic t bleeder failed. Was misting coolant and I would guess sucking in air when off and cooling down. Replaced it with a metal T but still had some temperature fluctuations. Took the thermostat out and it was failing internally. Could see a loose black o ring in it and it was a bit loose inside. The 180f one brought the temps down and doesn't fluctuate as much.

Follow up:
I tried the "topping off" method for a week. Each night, park on a hill, nose up. Each morning, open bleed screw and add coolant.
Results: No difference at all. No matter what, every morning there was air in the upper hose. Doing this actually caused my coolant reservoir to be over-filled, leading me to have to suck some coolant out.
Today it was 57 degrees out and this is what I observed:
Highway: NA
Neighborhoods: 198-200 degrees
Idling for more than 10 seconds: 205-210
My guess is the black 180 degree thermostat Atlantic British sold me isn't really opening at 180. Seems more like 190+
I guess I'll just have to live with 210 degrees at idle. I hope my head gaskets and cylinder sleeves can live with it
