I would say the temps vary by about 20 degrees. I think my cooling system passes the test you’re talking about. No part of the system is below 165F, which is uncomfortable to touch for more than a second.
It’s been 500 miles since the new cylinder head went on, so I re-torqued it. I also tried running without the fan at all. No change.
I’m not an expert, but my thinking leads me to the thermostat. I’m still not clear on whether or not it’s even possible that I have the wrong one, and that the bypass hose isn’t being blocked off properly. Any insight?
Is it at all possible that this is related to the newly rebuild carburetors? Would an overly lean mixture cause this kind of behaviour without obvious rough running?
