Injector size.

[84_GT350]

I'm inclined to agree. The 24 lb'ers won't really come in handy just quite yet (unless you've got some other mods). They really aren't necessary till you hit around 300hp (I'll just use that as a rule of thumb). You should be just fine still with the stock 19# injectors provided your car is mostly stock.
