Timing & Exhaust Port lower edge height

The pistons just clear the bottom of the exhaust port. I have about 600 miles on the motor at this point. I haven't rechecked the squash band measurement since everything has taken a set after a re-torque on the heads several times during break in. I should probably do that, but this issue has pretty much been there from the start.

Plugs read slightly rich to normal most of the time. Just did a plug read today after a ride while spending time in the happy spot (above 7K and mid throttle, it's really responsive). Right plug was slightly grey in color (almost perfect), left was very light tan and kind of wet, so a slight mismatch between cylinders.

Re-checked carb sync and it was spot on.
