No, they have bigger valves for a start and they are a different bore size. I also think the head is also different in that its allows for a bigger combustion chamber. Even if you can get them to work, using 3.0 heads will probably result in a lower compression ratio. Not a good idea.

They just won't fit, if you try you'll never find a head gasket that would work.
