I've read that the 531 head supposedly flows better on the intake side. But with identical exhaust. I currently own a SCP 530 head but have the oppurtunity to purchase a 531 for a very good price. My plan is to port whichever head out that I end up using, installing larger valves etc. My question is will both heads have the same maximum potential or will the 531 still come out on top at the end of the day. After I put all of the time and money into a head, I want the best I can get.
Thanks
