passenger side header to turbo seal?

[kens86gn]

Is there supposed to be a passenger side header to turbo seal? I also saw traces of black nearly all the way around the header to turbo flanges. I put my hand there when first started up and could feel hot exhaust leaking out with a slight tick. I see no evidence of any kind of gasket there. I pull only 10psi vacum at idle and seems like the car is running rich. There is exhaust spray marks on the driveway directly under the rear exhaust pipes. Is there supposed to be a gasket located there? Where do I find one? Could this gasket be contributing to some of these problems? Thanks for any help!

No factory gasket was there.

Turbo Riviera gasket is commonly used with good results but has just become discontinued.

NAPA may have something that fits I think there was a thread with a part number listed for one, do a search.

Or you could true the surfaces like many do without using a gasket.
