engine still not cool enough

Well I finally got to really drive the car a couple days ago. Drove about a 15 mile round trip with a 1 hour stop in between. The car didn't do too bad on the way there, ran about *195, still more than I want but on the way back I ran it a little harder, nothing excessive, and about a mile from the house the temp hand starts to climb. It went to *210 before I could pull in the driveway good. This thing is driving me crazy. I wonder if my 2 row radiator could be made into a 4 row. I think the cooling capacity is what is hurting me.
I read all the previous posts, and one suggested a High Flow thermostat, I have a 2 row aluminum from Jegs a high flow, Flowcooler pump, high flow 185* MR. Gasket thermostat and I have a flex fan direct drive, I have cast iron stock heads, water wetter, and my engine NOW will not get to operating temp, so I am installing a clutch fan, long story short I put all this stuff into my car cause it was overheating and now it wont get hot enough, so did you install a high flow thermostat??
