Default Intake/ fuel rail help please!

I bought a LS6 intake 12573572 for my 6.0 conversion. I also bought a LS2 stainless fuel rail, but the mounting points on the rail do not line up...they are too wide. I have seen this combo done on here many times....what am i missing? I need help here guys....why wont these line up?

Yup ^^^

I would put some injectors in there first. Isn't there a difference between the LS1/LS6 injectors and LS2? Height difference or something like that?

Does anyone make an adapter kit to make it work with LS1 injectors, or am I better off selling it and running my LS6 fuel rail?

If you have the LS6 rail, why not run that? The injectors are different heights...

I have been running this exact same combo for the last three plus years. Even if you don't bolt it down (not suggested) you will have to flex the crossover tube to get the injectors to line up but it will work. Just make your own brackets and things will be fine.

I'm using mine because I got it super cheap, the looks were a bonus.

Did I mention it also clears the truck coils with no problems?

My Holley rails came with 2 sets of brackets, one for ls1/ls6 and another for ls2 applications. The rail had 2 different mounting holes for the brackets with the ls2 being wider, the ls2 brackets were also a slightly different height than the ls1/6 ones. Here is a link to my install guide which better shows what I'm talking about.

By the looks of it, cutting them off or making an extra adapter is your only solution.
