I do have aluminum heads on my 496 with a Dewitts radiator. GM Water pump 19168602. Tried two different 180 thermostats, Stant and Mr Gasket.

Driving around town and freeway driving it sits between 100 and 210.

Any thoughts on what may be happening?
I would set the AFR around 12.5.1 I'd rather be fat then lean!!
