thanks for the input. i have had the radiator rodded, but am getting ready to buy a new one, the motor just runs TOO good for it to be a head issue (in my opinion), and i don't wanna tear it down unless i'm absolutely sure that that's the problem. this is a larger motor than i had before by .5 liter, and i suspect the load on the radiator is the issue. by the way, you can prolly get a new , used shtoud from www.collinsbrosjeep.com in Wylie Texas. They are a reputable and reliable when it comes to shipping. Rob
