Or a combination of these.

Different size shooters are available or drill yours. If you drill too big- which you may do if searching for the "perfect" size- solder them shut and re drill to the correct size as determined by testing. Then if you want, you might be able to buy a new shooter of the correct size or get one as close to the right size and drill it. This is because sometimes getting a good spray pattern from a soldered over and re drilled shooter is hard.

And again- you have to get a pump shot the instant the throttle linkage moves. You can buy an accelerator pump piston assembly separately, same page as above.
I do have the vacuum advance can going to full manifold vacuum. I heard so much about how full manifold is the way to go but I guess in my case it will help with the idle transition by switching to the ported. I wanna start looking at getting an AFR gauge. It would make tuning so much easier.
