ok i have a few questions but really they all relate back to the pistons. would the cc306 be to much for the stock pistons? im not sure if they have valve reliefs or not. and second what is the biggest valve you can go with with a stock piston with that cam if its not to big

 

I think there are quite a few guys on this board running the CC306 with a stock bottom end. That would lead me to believe you'd be fine. I know the stock pistons do have valve reliefs...I remember seeing them before I chucked them in the dumpster.
