According to your temperature readings, both digital and using the gauge, your thermostat is not functioning properly. Can you trust your garage to have followed the MGR refilling and bleeding procedure correctly when your oil cooler has been damaged in their hands? I'd suggest that you cannot. Once the possibility of an airlock has been ruled out then the evidence points to the thermostat. As you say this is new, it raises the possibility that the second-hand engine you have had fitted could have been contaminated with K-Seal. Here's my earlier post:
