Given that the valve cover sits partly on the intake and partly on the head, yes, you could be that lucky. Especially if the mating surface where the two meet has a dip or one is taller than the other.

I had a 86 Bronco II with a 2.9 Ltr that was the same design. The intake valve cover rail was 1/8" higher than the head. A generous bead of the right stuff was the only way I was ever able to get it to seal.
