Back in the day the Standard/Blue Streak "Jiffy Kits" or Filko brand carb kits were what we stocked and sold the most of..
"Tomco" was meh--they had some crappy accelerator pumps and gaskets but were useable if nothing else was available..
The kit will likely have several different top bowl gaskets,it is important to match your old one up,as some had extra holes some carbs needed,others had no holes to block off a port in the carb body..they give you all the possibilities to cut down on how many part numbers of kits you'd need to keep in stock..some kits used to come with foam block offs for the well plugs,probably don't now though..
A brass float would be a good investment also,ethanol can ruin the foam ones ,even ones supposedly rated for it after awhile,especially if you let it sit long periods..
