Your numbers don't add up.  Impedance increases by the square of
the number of turns but only linearly by the number of cores:
14^2 (196) >> 2^2*6 (24)

Hang on a minute, lets think about this.  I built a balun using one of
these cores or similar and needed 14 turns to get sufficient loss on 1.8
MHz.  This one has 2 turns but has 6 cores so it may not be far off.
