I am going to install a fast intake and need the cross over lines to do it. Does any one have the part # for these?

Not meaning to hijack but is can they be just blocked off or thats pretty much the only way to fix it?

Let me know whats the easiest way to do this guys. If I don't have to have the ls6 coolant line I would rather not have to buy them.

You can cut the line where it heads to the back of the valley cover. then weld/solder it to seal it. You only need to have the coolant circulating from the front of the heads to the radiator. for the back, cut the lines right at the plug and seal them the same way.

If you want the GM parts we have them:

Is the $33.50 for both the cross over and the plug or just the cross over line?

It doesn't remedy any thing the stock lines are just in the way of the intake.
