Post threads where they belong please.

I'm scratching my head on this. Either english isn't your language or you need to go back to school again.

If you are referring to the exhaust manifold they should swap fine, however that will only give you very minimal performance gains if any at all. You would be better off swapping heads completely for a better overall gain.
