2004 Jimny M13A High Temp after recon head and head gasket replace

Decided to pull thermostat out to inspect, as wasn't opening.
Looks toast, placed in boiling water and didn't open.
Considering leaving the thermostat out, running without.
As I live in remote WA where temps really drops very.
Thoughts on running without thermostat.

Running without a thermostat can sometimes mean that the engine never gets up to the correct temperature.

Whilst this is no where near as bad as over-temperature, you might find the engine is a little sluggish, uses more fuel and of course the heater doesn’t work very well (probably not a problem at this time of the year in WA).

There is an outside chance coolant flow will be so high that the coolant doesn’t stay in contact long enough for efficient heat transfer leading to local hot spots inside the engine, but I suspect this won’t happen.
