the only way i know to check for sure is to cut the intake open and look at the lines inside, the ls1 they are diagonal lines and the ls6 they criscross or the other way around something like that.

Something about cutting a intake open sounds like it makes the intake not usable, unless this is a term im not familiar with

Actually if you flip the intake upside down and look at the bottem it should be flat on a LS6, and if it kind goes up into the intakes, then dips down in the middle, the goes back up into the intake its a LS1. Do a search for "Ls1 Intake" and "Ls6 intake" Pictures should come up for both.

Here's a pic from Jerami's (JRP) FAQ thread:



The LS1 in the one with the hump (gold colored pads), the LS6 is the one that's flat (gray pads on the bottom).

I have a 2000 WS6, what am I going to have to do for the LS6 intake?I can use any intake whether EGR or not because its not needed correct?This one does not have the EGR adaptor.Do I just plug and hide the cord, or can I remove the whole dang thing?I also heard about the map sensor and coolant line being different, any ideas?

I might be wrong, but I believe all you'll need will be a LS6 intake coolant bypass kit, available from GM. It costs around $40.

i SWEAR to god i just put on a new intake that was like the one on the right, flat bottom. BUT, it came from a 2000 Trans Am stock, AND has the EGR port. i am 99.9% positive it was flat bottom cause i remember looking at it and thinking about the posts i had seen that made mention of the flat bottom

Here are some numbers that I have gathered:
LS6: 12573572; 88894339; 88890523; 12561184
LS1: 12560688; 12556333;

Endres book calls out P/N 12561182 for 2001-2002 LS1 but since I haven't actually seen one of these manifolds I can't say one way or the other whether it is a large runner (LS6) model or not.

SlowZ28...if the manifold that you installed was an LS6-style then you would have had to replace the coolant lines that run under the LS1-style manifold. If you look at the photo of the two manifolds you will see that the one on the left, the LS1 unit, has the marks in the brown foam from the coolant lines. The LS6 model does not allow enough space for these lines and therefore must have the rear water outlets/crossovers in the heads blocked off...only the front outlets are used.
