New fuel rails ordered, but will stock lines restrict me now?

I just ordered some new fuel rails, (BTW does anybody know the I.D. on profession products fuel rails?)

Anyways i have had a lot of people tell me to try replacing the fuel rails first to stop from going lean at the end of my runs. (which if you ever ever looked at the connectors that go to the fuel rails you will see that it has a very small hole for fuel to come out, pretty restrictive looking to me)

I just wanted to see what your opinions on this were. Should it fix the problem or not? I mean if this doesn't work its not like i wasted my money, i just start replacing the rest of the fuel system.

Also if any of you are interested. It cost me a little less then 350 for new fuel rails, fittings, braded line, aeromotive bypass regulator, and shipping... (pretty much a complete fuel rail kit.)

The stock fuel rails actually flow pretty well for what they are. The SN95 rails flow about 44% more than the Fox versions and can supposedly handle around 15# of boost before they start going lean. I'd imagine that you are right at the cutoff point for the capabilities of the stock rails. The new rails definately won't hurt but considering the power level you're at, I'd start looking at new lines pretty soon too (around AN -6 and -8).
