I bought the LS1 intake manifold gaskets. But, I don't know if I got the right ones or not. These are gray and the ones on the truck are orange/red on a plastic holder type thing. How do you replace these? It seems the stock ones are like one one each side of the plastic holder, but molded together through the little holes. Also, these are square. Here is a picture. Please help!

 

You need truck gaskets...the radix uses the car style ones. Basically use the gaskets which match your manifold.

I used some from the parts house and they looked identical to the factory ones. fill me in why did you get ls1 intake gaskets?

 

I thought they were all the same, didn't know. What's the part # I need? Do you have a link to the parts house? Thanks

 

gm part# 89017589. its $55.70 from gm parts direct. i am ordering it as we speak. I got the number from chevracer83 in his part number request thread. i hope its the right one.
