Running too hot!!

[DRASTiK]

Since I put the new parts on the car (heads, intake, injectors, AFPR, etc.), it's been running way too hot. It doesn't overheat, but it comes very close!! I bought a bigger radiator from the same guy that I got the heads from (kept his car cool with them), and that still didn't seem to make much of a difference compared to the smaller 3 core I had before. This radiator only has about 500 miles on it. The 160 stat that I have tested fine on the stove. I'm not sure what else to do. The waterpump I have isn't exactly new, but it's not really old either (almost a year old), and I don't hear any noises from it. Can it still be worn out even though I can't hear the bearings? If so, would a high volume water pump be a wise choice, or should a stock replacement work? Any suggestions?
