I suspect that it makes sense for you to get 185* at water inlet on block vs 150* at bottom of radiator, given that you were getting around 185* at outlet from block. It seems reasonable that the block would be (+/-) at one temp with the radiator cooling the water from the block temp to about 150*. I have no expert knowledge of this - just a guy trying to think about your problem. HTH
