i'd use the same gaskets that are on the manifolds now. i had no problem with re-using the stock gaskets.

I was told by the local performance shopp that bad things happen with gaskets on the ls1 for some reason. They suggested I use copper RTV on the head and the header and no problems will arise. It has only been a couple of weeks but it is holding strong.

Perhaps I should have clarified saying that they were referring to the junk graphite gaskets usually supplied by the header manufacturer. I asked what they used and they said the stockers are ok but are more expensive and they usually go for the copper RTV. They said they have never had a sealing problem using it whereas they had several blowouts on graphites.

Making a suggestion like that is far from making them a shop to avoid.
