Default LS3 Rails... FAST or Aeromotive?

I am looking into getting some fuel rails for my LS3 intake. I want something that will require no spacers. I have read in a couple places that both of them work fine on the ls3 intake with the stock shorty injectors. Is anyone able to confirm this?

I like the idea of the fast rails since they come with fittings.

The aeromotive rails look nice too though.

Will they both work on a stock intake with stock short injectors without spacers?

Mast sells rails that all come with the correct height brackets for any injectors you want

Still looking for more info before I dive in. I have heard/read that the aeromotive's will bolt right on to the LS3 intake with the stock shorty injectors just fine (no spacers or different modified mounts, etc). What about any others? Fast?? I don't know of any other brands.

If I remember correctly the FAST ones will, i think its 146033-kit for LS3 oem intake and rails(part description wont match) ..although Im not sure its offically on FASTs list. I think I was tinkering around one time with a bunch of parts and found they worked great for someone who really wanted FAST rails on his OEM LS3 intake and injectors.

Thank you for your input. I'm still undecided on what to do. Just want to figure out what is available to me before I lay the money down so everything helps!
