Difference between zhp head and m54b30 head

Looking to put a Lil more power on my 5spd 330ci. Does the zhp head bolt up exactly to the m54b30 bottom end

Yes perfectly,....BUT.

The only difference is the ZHP cams which are "slightly" better than normal M54B30 cams. I'd guess roughly 4 extra WHP, and my guesses are pretty good.

Moral of the story: It's not worth it. If on the other hand you were porting your M54B30 head & installing better/bigger cams, then you could see ~30 plus WHP depending on what was done.

It's obvious that you need to do more research on the subject. Start searching in the Driveline sub forum.
