If it's only started doing it since you put the clocks in and you're pretty sure that the engine isn't actually overheating then it's most likely the clocks. I would change them back and see if the problem goes away as a first step.

I had the same problem on one of my G40s. I changed thermostat and sensor but turned out the temp part of the clocks was reading high. On mine the needle never went all the way back to the end stop with the ignition off. The temperature and fuel part of the clocks is a plug in module. If you dismantle the clocks you can just swap the modules over.

The bit I mean is the actual temperature gauge in the clocks - with the needle and temperature scale. If you dismantle the clocks it comes out as a separate plug in unit attached to the fuel gauge. The speedo and rev counter gauges also come out as separate units. They are built like that so they can make up different clocks for different spec cars. The temperature/fuel gauge part comes in gallons and litres versions. The temperature /fuel gauge part out of your old clocks may still work even if the whole thing isn't working properly.
