Are ls2 actually better. Do they flow more and can support more power?

I believe they do flow more-question is will they fit on a LS1?

well a ls6 intake will fit on a ls2 so I assume yes they will. Pretty much everything will bolt to a ls2.

Yes LS2 fuel rail will fit on LS1 but you need a spacer kit to lift it up ( because LS2 injectors are shorter). You also need fatter O rings. Some brackets need bending to fit.

A LS1 Intake will fit on a LS2 as well... not necessarily the Rails.
You need a kit, like the one mentioned above.

Here are the LS2 Rails on the L76 Intake. I had to shim them up 1/2" for the LS2 Injectors. The L76 Intake is made for shorter Injectors.
