I knew from the forum that the aftermarket sending units were not great so I asked my builder who did the bottom end of the L-82 355 to check the AFR heads and tap them for the OEM sending unit.
BTW-The AFR heads were perfect right out of the box which is what I expected since they are pretty much the best heads and expensive.....There was a lot of paranoia around using heads right out of the box at the time in 2014 since lots of folks were using cheap china aluminum heads with casting problems, cheap valves and springs etc. The AFR's were the bomb and still are......

So my problem could be still the sending unit?!? I measured with IR gun on water pump but maybe the iron is warmed by the engine more then water… how to measure the real water temp?!?

I measure with my IR gun on the thermostat housing. Hottest temp before it goes back into the radiator.
