Which FAST Fuel Rails

my question is, im using LS1 style injectors. so which fuel rails from FAST do i need?
1. the LS3 style fuel rails with adapters
or
2. the LS1 style fuel rails
seems like either one will work, (obviously the LS1 rails will be cheaper since i dont have to buy the adapter kit) but im wondering if you HAVE to use LS3 fuel rails with an LS3 style intake, or will the LS1 style rails work with the LS3 style FAST intake.
