Demon Carb Mods

I have a Mighty 650 on my 365 ported edel heads, comp solid cam 252-550, 3500 stall, 3.91. It seems to me that this engine needs a little more air/fuel. Is it possible for me to change a few parts such as the venturi, high speed air bleed, and booster to make it flow like a 750. BG's website has a page that shows spec's and there are only a few differences between a 650 and 750 mighty.
