20 or 18's?

['04limited]

since i rebuilt my motor and had my cylinders done by herr jugs i have been running 20cc domes in my cool head, i have a brand new set of 18cc domes that i purchased at the same time, but decided to run the 20cc so i wouldnt have to run race fuel, would there be any downfall to changing to the 18's and running race fuel? I know all the benefits just wasnt quite sure if there was a down side.

I would talk to Kevin about running smaller domes and more compression since he did the motor work.
