modifying ls6 intake to 00
modifying ls6 intake to 00 what is involved with the coolant lines when i do the ls6 swap onto my 2000 ws6? do i need to grind the underside of the intake (and how?) or should i go with the new coolant lines? and if so wheres the best place to get them? thanks!
Look at this http://ls1howto.com/index.php?article=18. As an aside, all of the articles on this website are excellent.

You can keep your stock coolant lines with an LS6 intake all you have to do is grind all the ribbing off the bottom and then take all the clips and black laced covering off the coolant lines and lightly tap the coolant lines so that they start to oval. That's it, I've done two cars like that with no problems.
Just buy the LS6 Coolant lines and be done with it. You will alter the structural integrity of the intake if you start shaving the ribs off the bottom!!! It has been done but I would not recomend it.

Im doing the same swap on a 2000 and decided to swap the lines. I bought the intake from a friend and luckily he included the new line and block offs. I cant imagine they cost much and I always try to do things right the first time, grinding the bottom and reshaping the old lines seems kinda rigged and ghetto to me, it cant take much more time or money to swap them...just my .02

Dont waste your time and money.... keep the stock coolant lines. I have knocked the ribs off the bottom of the ls6 intake to install on a 98-00 setup several times.... no problems. Dont waste your time and money on the coolant lines. I also scrape the foam pads off the ls1 intake with the chisel and glue them in the same position on the ls6 intake.... to keep dirt from getting between the valley cover and ls6 intake.
I took a light hammer and small chisel and knocked off all the ribs, then took a light hammer and lightly tapped the lines until they started to flatten out, ( the intake did NOT sit flush with just lack of ribs on mine ), then I checked the intake one last time to make sure it sat flush on the heads, that was it and it works fine. As for the comment about the little spongy pads needing to be put on, if you buy the Fel Pro intake gasket set it comes with new pads to install. So rip those fuggers off.

I just got a hammer and a large screwdriver and chiselled the ribs off. I was scared of damaging the intake at first but it is extremely easy and quick too (10-15mins). Mine sat flat without altering the coolant lines at all
