LS6 intake/Coolant pipe & plugs question

![Question](https://ls1tech.com/forums/images/icons/icon5.gif)
I will be installing a LS6 intake soon and have seen that most people use the coolant pipe and plugs kit because of clearance issues. My question is, since you are blocking off some of the coolant passages, won't this be bad for parts of the engine and possibly overheat in some places? I'm not sure of the path of the coolant lines back there but it just seems like a bad idea to be blocking off coolant ports![Icon Confused](https://ls1tech.com/forums/images/smilies2/icon_confused.gif)
Also, I know some people just grind the bottom of the LS6 and tap the line down. Will this always work and should I just save some money and do it this way?
Thanks everyone

Yes, people say that there are problems with the two rear cylinders, especially number 7. Just take a hammer and a chisel and knock the ribs off. It takes 15 minutes and will save you 60 dollars from the coolant line and plugs. I actually just took the ribs off 10 minutes ago, very easy. I used a hammer and flathead screw driver.

I did the ls6 intake modification method (rib removal and coolant tap down) and its been flawless so far...
Make sure that you take your intake and place it on the heads (without the gaskets!) to see if you clear the coolant pipes. Once your intake is sitting flat without the gaskets, put the gaskets on and torque it down.
tip: there are some plastic clips holding the knock sensor harness that should be removed and replaced with tape... My ls6 intake didn't clear those.
