Could this idea work ? Did other guys did this ? 318 infos

Thank you, on other opinions this 350 cfm carb could make me loose some low end torque as i read on other sites...my 1st idea was to be conversative and make the little 318 breathe a bit better with some better tiny flowing heads / better carb ( cfm ) and headers etc...i just didnt want to spend a ton of $$ on a 4bbl carb since i have 2x bbds and this one laying around
