So do B58 fit?

I have stock N55 Eldors and I have to admit, after 2 years of them I have not had even ONE misfire. But I am thinking of replacing the coils in my daughters stock N54 so I may get the B58's and just give her my Eldors. Do the top B58 coils fit the N54 plug and play or do you have to mod stuff? I would really like the most powerful plug and play option available. I don't care to mod stuff and rig up the springs, etc. I also plan to upgrade from my 17T's to maybe 19T's or Frankenturbos soon, so I may as well make sure I have the right coils.
