There is a less expensive kit specifically for the 6 pack , it is around $28 each , you can often get away with two of those , even three is not overly expensive compared to that kit , I do not have the part # handy though .With that kit you should get both of the base gaskets needed & 2 of three needed float valves / needle & seat assy so two kits will get enough parts to do 3 carbs
