Hey Guy's

I have a truck intake manifold I am planning on putting on my LS1.

The manifold part number is 25383922 and it's from 2006 to 2008 ish truck engines from the research I have done.

I need injectors for it, I have found the part # that matches the manifold to be 12580681.

I was planning on using injector part # 12576341 as they flow more and are available in Australia.

My only issue is that in my searching I have found that the truck injectors are slightly taller. Please see (http://www.nookandtranny.com/Images/...s/dsc03343.jpg)

Also wanting to confirm that these will be what I need to get the LS1 harness to work with the new injectors. (http://www.ebay.com.au/itm/EV6-EV14-...item58b42686f2).

Can anyone also confirm if I need special truck manifold bolts? And can I get away with just making the manifold gaskets?

thanks heaps, Clay
