if you are gonan wire teh 6 ports open, instead take the sleeves out, and remove teh shafts from the lower manifold and block off teh holes that it would create. this will be good for some top end power, wiring them open will just take away the low end

if you went with 720s you'd have too much fuel and your car would run poorly. Then, in order to fix that, you'd use your SAFC to set the 720s to put out fuel like a 550, maybe less.

The most efective way to run a SAFC is to run large injectors and pull them back, oposed to the needed injectors and bumping them up.
Who ever told you about the 550cc to 720cc might have been tinking this I dunno. I say ask someone who has SAFC exsperiance, with ported motors and so on, like Aaron Cake or SonicRat.
IMO the mods you listed are not anything major, or requiring alot more fuel from a allready right engin on normal duty cycle.

No reason to go with larger injectors unless you are actually leaning out. And it's doubtfull you will ever run out of fuel with that port configuration (though it HAS been done on occasion).

If you use a wet nitrous kit (and you should) then the extra fuel is added through the nitrous nozzles, not the injectors. The injectors will be fine but the fuel pump might need an upgrade.
