Get the Professional Products LS2 rails. They are cheap under 100 bucks. Fit nice. Plus they are bigger than stock. I am going to run LS2 and Nick Williams 90 on my LS2 402. Haven't got it running yet.

What intake do you currently have?
The LS6 intake will make more power, even with the 75mm throttle body.
But, to swap a stock LS1 fuel rail, you will need new lower injector o-rings as the injector bosses are larger, and spacers between the fuel rail and the mounting spots in the intake. I dont remember the exact dimension but I believe its around 1/4" to 3/8" spacer needed.
