Default Fuel Rails

I'm biuilding an APS Twin turbo car, my goal right now is to make approx 650 HP

I'm planning a lonnies intank twin pump setup 60 pound injectors, and hardwier -8 fittings. (not braided stainless normal metal fuel lines)

I am pretty sure i'll have to upgrade my fuel rails right? what would the better upgrade be? LS2 rails? or aftermarket. so many aftermarket make me mad because they are -6 fittings and really just for looks.

What are the size differences in the LS1 v LS2 rail?

thanks!

I looked on their site, 3/8th's which is -6 vs 5/8th's (-8) ( sizes are approximate but really close i believe)

does any one else have experience with these? Looks a lot better than paying over 200 for others if not needed.

injectors are too tall and you would need to rig where they bolt to the intake.
