I hate it when people open up with this, but do a search on Professional Products. They make okay power b/c it's just a rip-off of an Edelbrock intake, but they are horrible quality. They castings are bad and so is the machining. Basically save a little more and get an Edelbrock intake.

24# injectors will only make power if the rest of your combination needs them. I'm running 19#ers on the combnation in my sig and they've done fine so far. To answer your question: by themselves, they don't make a difference.

I've got a Lunati #15014 and it idles decently, and has a decent midrange power curve. It works well for a street driven 302.
