Replacement carburetors ?

Hi all,
Have searched the forum for info or tips about this issue but didnt find anything
Anyone that could suggest suitable carburetors to replace the stock carbs on one of my "projects". I have found out at kz400com site that the stock should be Keihin vb32. The replacement should be relative easy to tune with pod filters. 
 

Why do you want to replace them?

There is no "easy tune" on replacement carbs with pot filter only to look like a cafe racer bike! Cleaning and rebuilding the stock carbs is the goal. Pot filters are very difficult to tune without a dyno, O2  sensor  and knowledge to give you the corret air/fuel lambda ratio (13,7). 

Thx for answers.
Have two Z400 Ltd 1982, One in relative good condition that will be restored to its "glory", To this one I have the stock vb32 that should be cleaned and restored. 
The other one i in not so good condition and also, I do not have any carbs to that one and need some replacement. The goal with this one is something fun,  like scrambler or whatever.
So the question remains, need some carbs...
