what do you actually need ot replace? Honestly the only hard parts I ever replace in the carbs are the float needles and only after they have a pronounced groove worn in them (occasionally I will have a sunken float too). Those kits are usually only good for the gaskets anyway.
Can't help you on the carb question, but I can say that the dealer will sell you individual parts instead fo paying for jets that are the wrong size and needles you don't need (and will likely leak).
