Welcome! My 2c on carbs
32/36 is very capable. Rejet for use with a mild cam and remove choke butterflies. Being a progressive carb it's very road friendly. The first thing I'd check on yours is the idle jets to see if the threads in carb body have been stripped which would cause the lean running condition.
38DGAS has a sudden throttle response. Back to back with the 32/36 I only gained about 0.2 sec over the 1/4 mile but it does have a sportier feel (and sound) to it.
Twin DCOE's are either for show or for cylinder heads that have been ported, bigger valves, higher CR etc. With a reasonable budget, 130WHP is about the average you'd expect from going down that path. It's easy to get sucked into the idea of getting big power with twin webers but there are pros and cons.
Build a mild, reliable motor with a 32/36 and enjoy many years of trouble free motoring.
Build a highly tuned motor on twin carbs and expect fuel vapours and a strip down with new rings every couple of years lol
