Coolant pipes? ("H" looking hardlines under intake mani) Refering to the hard lines in this picture:
What is their function? I thought a saw a picture of a car with those completly blocked off, i may be wrong. Reason i ask is, i have the FAST 90 intake mani which doesnt allow for clearance with the hard coolant lines in place. Sooo my questions are:
1. what are they for?
2. Can they be eliminated?
Thanks to all that help!

You want to get the LS6 version. That was what you saw that was blocked off looking. The LS1 style you have to flatten with a dead blow hammer and even then you might have a vac problem just from not seating properly.
PS:
Are you cold or something?
If that is even you in the picture.

nah, thats a generic pic from ls1howto.com 
Instead of the mad rigging pictured above, could i cut off the middle tube and weld up the holes on the side tubes? Again, what purpose do these things serve? I know the front feeds coolant to the TB
, which has been eliminated. thanks

The purpose is to vent air on fillup and to vent steam should any build in the system. There's some debate as to why it flows through the TB, but removing it does no harm.

I snip'd them off with a pair of 9" Klein pliers, then crushed the end shut with the end of the pliers, then I mig welded the seam with a flux core welder. It took some finesse.
It actually came out really nice. I left about 3/4" on the rear ones (plugs), then I bent the little stubs down after I installed them. I also bent the front tube down as well, even though I probably didn't have to. This method worked VERY well and was free. I'm sure you could figure out a way to do this without using a welding machine too.
The front pipe looks like it would actually work better than a stock 01+ tube that most people put on. I had a problem with my 01+ tube hitting under the throttle body on the FAST 90, so I had to bend the hell out of it.

OMG! Too funny! We have an 89 Camaro and get this: the bottom of the block cracked and water was spewing out: we used JB Weld on it and it has held up for many months!

That's crazy! Hey man, we took the ENTIRE 90/90 off and re-installed it because it was not making a good seal cause of the LS1 coolant pipes underneath. The "girl" runs like a charm now. We went to the dealer and bought the LS6 set-up coolant pipes and they work great, because they are only on the back and front of the manifold. I am going to get the part #'s tonight and I really think they should make a sticky with the part #'s if they already have not. I am taken her to the track tonight and she will probably run like a charm! Thanks for your help!!
