LOL, yes the factory ls1 intakes arent worth much but they do sell for prices between $50-$100 pretty easily. Which would help the OP out a decent amount when he can pick up an Ls6 intake for $300-$400 used.

I've copied our response to a similar question on our LS1Tech Porting Special thread: https://ls1tech.com/forums/sponsor-s...y-porting.html
It's post #20 if you want to go there. Otherwise, here it is:
Many say the LS2 intake manifold is a step backward from the LS1 and they are right if you consider simply the stock unported LS2 manifold. The reason for this is that the LS2 intake manifold switched to a new process that sonic welded three pieces together. The result is that where the pieces joined together they rarely butt together properly and there are ridges and bumps that disrupt airflow. However, porting the LS2 manifold smooths all of these transitions. Basic Porting of an LS2 manifold will generally get up to 5 rwhp better than the LS6. Our Radical porting of the LS2 manifold generally gains an additional 5 rwhp over the basic porting. For the difference between Basic and Radical porting, go to our web site at http://www.peakspeedshop.com/
Another advantage to the LS2 intake manifold is that it allows you to step up to a 90mm throttle body from the LS1 78mm throttle body. The cost of the LS2 intake manifold is less than an LS6 manifold, however, that is offset by the additional cost of having to pick up the LS2 fuel rails, injectors and throttle body as well as the cost for porting. In the end, though, it is my opinion that you will have a better intake system than the LS6/78mm setup at about half the cost of a FAST setup.
That's not saying that we're not a fan of FAST manifolds. They are a quality product and we also port them. However, if you're on a budget and looking for the biggest bang for the buck, switching to the ported LS2 setup is a great option for LS1 owners.
I hope that is helpful....
