I rebuilt my top end this summer and not sure if I need to worry about this.

I started the sled the other day and noticed vapor coming out of the exhaust manifold where it enters the muffler. It's not a lot of vapor coming through, but enough to see when the engine is cold. It's only coming out of a small area, not the entire area.

Should I take off the muffler and resinstall? Maybe that ring (gasket) is not seated correctly?

Nope it will stay soft and rubbery and all you need to do is peel it off if you need to remove the exhaust and reaply when you put it back on.
