We never went that big, just 1.6 and 1.7 on the exhaust side. For whatever reason (exhaust scavenging manybe) seemed to extend the hi torque range by about 800 RPM on the dyno. Probably nothing that would ever matter on the street.....???? Coil bind does become an issue, along with tipping the rocker past the center of the valve stem.....
