What's all needed for LS6 intake swap? Ya, I searched
I'm going to buy a LS6 intake very soon. What's all needed for the swap? I was going to keep my stock coolant lines and chip out the bottom of the ls6 intake. I've seen a video on here where the guy did that. So I can save money there! Thanks for any info guys!!

The main thing needed that you won't find on a parts list, PATIENCE
I ground the fins on mine, reused the injector o-rings and the manifold gaskets.

theres no pics needed. i took off all the fins. u dont need them. once u do it your gonna see how easy,fast it is, and your gonna wonder why anyone makes a big deal about the stupid fins to begin with.
just remember to disconnect the wire harness in the back of the intake and be very carefull of the oil sending unit in the back. once everything was disconnected i used a big prybar to lift the old intake up off the block. once its lifted up wiggle and pull it out. but be as carefull as possible.
its not really all that bad. if i remember correctly the #8 spark plug was more of a pita that swaping intakes

I'm surprised you needed a pry bar to get the intake free from the heads...mine just kinda popped free when I tried to lift it.
I also just took the fins off the bottom of the intake...I think they do serve a purpose of strengthening the floor of the manifold...but it's been about a year and 40K+ miles in my car without being an issue.
You will need an EGR blockoff plate for your exhaust manifold, OR an LS6 intake modified to accept EGR (I'd recommend the plate).

Yeah, I just got headers, haven't installed them yet...so I had to do the same as you when I swapped my manifold...if you are using the plates (I've never heard of threading bolts into the holes, my holes weren't tapped, wouldn't want to risk cracking a manifold) it's worth having new gaskets for them too.

not to hijack the thread, but what is everyone talking about with the oil sending unit? Is it an electrical connector? Is it a hose or line? Im doing this install soon and i just want to make sure i dont screw it up. Thanks.

So all I need to do is chip off the fins, get new gaskets and bolt the intake on? Plus put the egr block off plates on? Sounds easy to me. I'm good at working on cars. Just sounds like it will take some time. Thanks for all the help and tips guys. And a big thanks to MjMaro. The links are a great help.

Yeah pretty much...and swap the injectors from one manifold to the other (put oil or grease on the O-Rings before you try to stuff them into the new manifold).
Be prepared for it to take a few hours, keep everything as clean as you can, have a vacuum ready to clean the heads thoroughly when you get the old intake off (there's always crud you can't see till it comes off).
Another tip, the intake manifold bolts pull up a little bit out of the manifold quite easily to a point...and there's NOT enough room to get them completely out of the manifold under the cowl in an f-body...so as you loosen them up, have a piece of tape in your hand. Unthread the bolt from the head, tug it up as high as it will go, and wrap tape around it so that it won't fall back into the manifold/head.
Do the same thing to the bolts on the new manifold (tape them up before you put it in) and then remove the tape after you're confident the new manifold is in the right place.

The vacuum hose which goes to the back of the intake manifold is routed behind the OPSU, so if you are not extremely careful of getting the vacuum hose over the OPSU, it will snap off with very little pressure. I was conscious of the OPSU and still managed to break it (costs $40 IIRC). Not a huge deal but very preferable to avoid the headache of dealing with it at all.
