The A6 and B2 heads are the same casting, part number.
Use the ZC cam in the ported head, shouldn't be a problem... in fact,*SHOULD* be better than what you're running now... I'm pretty sure the B2 head is PM6 as well, but you should look... if the part number is the same, it's the same head casting, e.g. same valve ports, etc.the only thing that would be better about it is the port matching/polish job that was done to it...
