16v or 12v and alt.

I'm currently running a 12v no alternator. looking to replace the battery I would also like to put on an alternator. but I have been reading that some are going to a 16v without an alternator (no belt to worry about) also looking for pictures of alternator mounting with elephant ears. looks like the money will be about the same as I will need a charger for the 16v. thanks for your help.
