I just bought one. They are supposed to cool better and they definitely have to make more power since they combustion chamber size is decreased. I am having a problem with getting my head gaskets to seal, but it's unrelated to the head itself. It looks real slick on this motor. I've never liked the red. The blue looks awesome.

Another thing is Mountain Performance doesn't even have half of the stuff they show on their website anymore. If they don't have it or if you'd rather just order it direct here's Peak's number:
