Well as far as the thermostat goes its defenitly the right one, because they are different then the average thermostat. Its possible that its stuck half way though so I will never know unless i crack that open again and test it in hot water.
As for the coolent cross over, I cleaned that out by using an air compressor and blowing air through untill enough crap got through.
Another idea that I had was, is it possible for uncoated headers to generate enough heat to throw off the coolent temp sensor in the head? I replaced that one sensor on the drivers side head when I finished everything up, but it is right between the first 2 primary tubes. Just another idea, I have been montoring my fluids and the color is still very clean, no leaks, no over-flowing. Everything seems normal on the surface.
It still does it to me, its very bad on the highway but around town, it keeps a normal temp, and if it does rise it goes back down rather quickly.
