I don't think overfilling would be helpful on this engine.
This. Same thing I've found out about our engine as well.

On wet sump engines, people usually put close to a quart over (mostly to avoid lifter tick).

With maintaining accurate oil levels (3/4 on the dipstick range). I never got lifter tick on any autocross day or track day.
