I have LS1 billet rails on my LS3 intake so I would say it is doable.
I only had to modify the mounts a little.
The stock LS3 rails look better and bigger than the LS1 but I am guessing you would not need them before 800 hp or so.

Not really sure. I just used the LS3 rails, cuz they were $75.00 off of ebay vs. the way-too-damned-much for the Fast rails....and they fit my intake with minor issue.
What kind of power are you wanting to make? Unless you're going FI, the stock rails are usually pretty good...up to 750-ish, IIRC.

Any one know if the fuel rails for a FAST LSx or LSR will work with the factory LS3 intake?

I know it say not for factory intake but why?
