Suggestions on performance upgrades for 225

Thank you everyone for the great responses. So if I'm getting this right, a 2bbl carb versus a 4bbl is recommended, with dual exhaust?

I'm hesitant to do any cam work until I can find a mechanic that can accommodate the work.

Any recommendations on a manufacturer for both intake and exhaust manifolds? And who makes the best 2bbl carbs for molar?
