I used a 15 mm socket on the passenger side then an open end 15mm on the drivers side. You can but the bolts and seal as a kit from the dealership or you can buy a new steam pipe with bolts and seals all included. you can also get them from gm parts direct but if your in a hurry go to the dealership, as gm parts direct took almost 14 days to get the part delivered to me.

 

got the seals from the dealer, cant remember how much but i think they were 3 or 4 bucks apice. expensive for a washer imo.

 

Count yourself lucky. I just spent almost $10cdn per seal at a recommneded Pontiac dealership here in Toronto. I was going to go with gmparts direct but they don't deliver up here yet.

I also thought I heard someone say you could get the seals at NAPA by the bag for a much more reasonable price but they don't stock them in Canada (not sure about U.S.A). I like the gasket paper idea but am not very confident of my skills in tackling it. Anyone have any pointers? Where do you get gasket paper? I wonder how dependable that option is.

Any other solutions?

 

yeah man i hear you i just broke down and bought all the factory stuff i dont feel like doing this again it was like 3 something for the bolt and 11 bucks each for the damn seals why they are so exspensive i don't know but i would rather have the right parts on the car.

 

Any Chevrolet dealer has them.

 

Well i got my new bolt and seals at first the car was still leaking but i tightend it down alittle more and it did not leak and i had the car running for 30min's but it seems when i was tighting it it felt like i could tighten it evan more but i did not want to because it was not leaking at that point and i could not drive my car because the 4 inches of snow on the ground lol but all i have to do now is connect my header to my ypipe and it should be good to go now all i have to do is figure out how the hell to get this header to stop rubbing against my steering linkage on my mid headers from pacesetter. I would like to thank everyone on this board for helping me out through this whole headgasket install

 

This is of interest to me as I am about to install the same headers. If you have found a way to stop the rubbing please post the solution.
