Cab, im using the ICON pistons with a 12cc dish. I don't think they are the best quality piston to do that with, not sure. That sounds like too much trouble for me, but thanks for that idea guys. Cab, didn't you have a set on these same E max wedge victor heads that never performed to your liking? I'm really contemplating new heads. Might fix all my woes with these heads. Will see.
