yes. You could probabally get away with the 30# ford red tops for pretty cheap

You can probabally find some used ones cheaper. I bought some from a good friend with 3000 miles for $90 but that was a really good deal

the later model stock s/c gtp injectors come out to be ~39lb @ ls1 fuel pressure (58 psi i believe)...they can be had CHEAP on the gtp forums, but you have to buy 2 sets because there are only 6 to a set haha. maybe check ebay? that would be my suggestion. they will work jut fine, a friend of mine is using them with a tfs 215 head/donkey dick cam/fast 90 setup with NO problems.

Let your tuner check your duty cycle before buying injectors. Why upgrade if you don't need them?

I have the mods listed below. I went with #42 injectors from stock.
My duty cycle was over 85%. Now it runs around 50%. I bought mine from HSW at a good price.

Get the green top 42lbs. You will need them. Make sure you get a tune before you drive with the new injectors. It will be way to rich and you will wash the cyl walls

#30 ford SVO red top injectors. <$300. You will need them with those mods. You need to put them on at the place that is going to tune your car for them. You can't change injectors and not have it tunned right away.

If your setup is worth jack ****, you'll need the injectors. I wouldn't wait to find out either...
