[QUOTE="LargeOrangeFont, post: 9099479, member: 22835"] I dont have the head cooling mod and have had no problems on track so far. I would not even call the head cooling mod a preventative mod for open track use. If you run a tune that is not on the ragged edge, you probably won't have head tick issues. The valve guides get hot and wear because of hot valves caused by high EGTs, not high coolant temps in the head. There is no water directly cooling the valve guides. As far as the aftermarket radiator, it didnt hurt but it did not really help either. I run with someone who has a nearly identical setup to mine, and we see little difference in coolant temps on track. On the street it seems to help a bit with bringing temps back down, but nothing dramatic. [/QUOTE]
