have you verified that the temperature gauge is accurate?
I find one of those lazer temp guns to be very helpful in these situations, but you can even use a meat thermometer.

Secondly, what do you consider "too hot"? Years ago temps of 180 to 190 were average, now 200 and 210 are pretty much normal.

Lastly, what are you using for a thermostat? Not one of those cheapy poppet styles I hope? If so get yourself a good sleeve type thermostat, it can flow more coolant and is far more stable to keep the engine at an even temperature.

I'm not sure why you chose the electric fans but if you still have the parts, go back to the engine driven fan with a full shroud over the radiator to maximize airflow across the radiator core. The electric fans place the same load on the motor through the alternator so there is no real gain in horsepower. Electric fans work okay when there is no room for an engine driven fan.

I'm not familiar with your cam or the rest of your build so I'll stop here for now. Others will be along and offer more advice. It's nice to see you here too!
