No presoak is needed for Ilfochromes, and in fact, might be
counterproductive.

I use a pre-soak all the time for about a minute.  Actually, in their
literature Ilford recommends a pre-soak for  prints 11x14 and larger. They
say " for larger prints, pre-soaking is mandatory because of the larger
surface area that the developer must cover quickly and evenly to avoid
streaking.  If you plan to make larger prints, you may wish to consider
pre-soaking all of your prints in order to establish a standard working
procedure for all print sizes."  I used to occasionally get streaks or spots
on some of my prints so I practiced their recommendation.  Hope this helps.
