The 30's would give you a little more breathing room if you have any notion of future expansion, but you could use 24's no problem.

I would base my choice on whether or not you'll be adding more power later.

My experience tuning various combos has shown that you'll be ok on the 24s if you are keeping it under 6500 with the stock fuel pressure.

Unless you have a killer deal on the 24s, I would go 30s or larger if you're getting it tuned or have a "calibrated" MAF. (go for the tune)

Shoot for some 30 lb injectors.

I am not sure if Ford Racing makes them anymore.

Yes they do, and I go 30's. More room to grow later on unless you go boosted then you have to go 42+

That is nice to know.

I just have noticed that Summit does not sell them anymore, although they sell others.

perhaps not everyone does anymore but you can still find them pretty easy.
