I would say that the stock returnless rail would work for you, but if you plan on building more horsepower in the future you may want to upgrade. I was making 400 rwhp on the stock returnless rail, pump and injectors and all was fine.

Returnless unless you really want to do a full fuel system overhaul.

You can use your stock rails with the intake but if you wanted a different look we have a kit to install our rails(or any rails) into your factory setup.
