I know this was listed in the _ease thread but, since it isn't around anymore, I will ask again. What gasket is best to use between the manifold and turbo? I tried the high temp silicone and it now leaks so I want a good gasket to put in there. I know some guys mentioned a Riviera gasket but I need a part#. Also, is this gasket a flat gasket? I like the copper gasket I got for the turbo-d/p from ATR and would like something like it. Thanks for the help and sorry to mention that name...
