They claim a coolhead will help your engine run a little cooler, I don't know if that is true or false. I bought one because I can run whatever dome in it that is needed for my setup. The domes come out of the head so you can change them to a different cc. Basically changes your compression, I have 20 cc domes in mine and I have 150 psi in each cylinder. Not sure what the break off point is on compression, everyone has a different number. If you go with to small of a cc dome then you would have to either run 50/50 mix race fuel and gas, or straight race fuel. I would say I'm safe at 150 psi because I have ran mine on 91 octane for about 7 months or so now. That's all I know about it. :biggrin:
