Are you sure you don't have a leak in your adapter plate?

That's perfectly normal if there's any air leak, which you just created, in the exhaust and why a bad header gasket can kill a motor. If I pull the bung plug out of my header while it's running it will soak my hand in seconds, but when I kill the motor and remove the bung plug it's dry and sooty. I was freaked when I saw that much water come through but it's normal.

See learn something new every day, and now that someone said it, it makes sense.
