I would say about where your at, I don't see any kind of ignition magnifier. Maybe 34 but I doubt you will notice.
You got some plans for that, You did head work right?
I'm not a 2.3 guy, so maybe someone else could answer.

That's a bit wide.  Pull them into .028-032"

EDIT- Well I guess I should say, that if they feel fine, and you're not having any spark blowout under boost, then the bigger the gap you can use the better.

Ford specs .028-.032 for the 2.3T...

Likely after a couple months when the plug tips "round off", you'll start getting a misfire at higher boost levels...
