look for the smog pump port at the front of the manifold (directly infront of the tb), if it has a hole or a plug then it is an ls1, if it one piece of smooth plastic than it is an ls6. Just a quick easy check. I sell those for 300 all day and usually have people waiting for the next one to come off. If you can get it for 200 get it. If you dont want it for 200 i do. thats a steal.

I think ls6 intake don't have egr and ls1 do. You can also tell by looking at the bottom of manifold. U could check the part no.
