14 hp Briggs, performance parts or replace?

I am not big on the briggs, but have always believed if you think you want or need bigger start with the bigger engine then hop it up. that is my theory anyway. I would image this is true to the briggs as with rotax or yamahas , there are always things that can be done for example bigger and dual carbs, porting, stroking changing rods , pistons , heads, exhaust, dual plug, big boring it or at least max bore for the sleeves you have

all and all you would be easier just starting with a bigger engine in my opinion

First off, there is nothing wrong with my 14 hp Vanguard, I just want more power. I don't need huge, just something in the 18 to 20 hp range. The question is, would I be money ahead just getting an 18 hp or make modifications to my 14? What will it take to get 18 hp out of my 14 hp? I know the difference between the 14 and 16 is the carburetor, what will it take to get the other 2 hp? All opinions welcome.
