Manifold sag

[29closedcab]

How much manifold sag is too much?

 

[Fred]

I would say, "ANY" along with EGG shaped port holes..

When the #4 ring won't fit the recess then it's too much IMHO, but I'm still running mine without the #4 ring in place.

It's (the rear exhaust port) looks to be about 3/16 lower than the rest. I think it might be me fr a new one.

Will the late 2 piece copper gaskets seal it??
