82 degs, no thanks, my V6 runs at 95 with the original type 88 deg thermostat.
Rather than buy a new thermostat, which are all 82 deg ones anyway, explore Stocktake's suggestion of adding an in-line thermostat.

I've just reclaimed an old thermostat from my donor, rather than buy a fake "Genuine/OEM/MG Rover/Xpart" not up to original spec thermostat. A whole lot of effort but in my location it was either that or an in-line thermostat.
Good luck
