I have an all stock 86 motor in my r, it has a 66.5mm bore. I would love to get a big bore pro-x cylinder eventually, but right now thats not in the works. I have a chance to get a pro design cool head with a 20cc dome for pretty cheap. The thing is that the cool head has o-rings. Will this be compatible with the stock cylinder i have now? I cant find this info on the pro design site sorry. thanks..

Yes that cool head will work good on your stock cylinder. The o ring head will cool better than a head gasket and it will seal better too. I had 2 before I went to Sparks PV cylinders.
