I also have another 3.2 in process (I am beginning the smoothing of the ports), and I need to determine the size of the header (TT) flange. Now where is that box?

No the 3.2 exhaust port ends up effectively being 40mm due to the recess for the flange protrusion on the stock HE's.
So you end up with a 40mm port feeding into a 35mm opening.
It's fine on a 3.0, since they all had 35mm exhaust ports.
