Cast Iron 440 Manifold Washers

Where do the conical washers go (if any) when installing stock cast iron manifolds to stock heads? All around, only on the end exhaust ports or not used.
My drivers side manifold does have a vertical crack in the center when I took it apart and it did not have any conical washers on it at all. I dont want the same thing to happen with it's replacement.
Anybody know the right way to do this?

I found it.

No stock BB Mopars I've seen have had washers(of any type) like the SB come with on the exhaust manifolds, not from 1958 up to 1979

No washers on a BB. Small blocks had them.
