Chris: I don't use a V35 and so can't really say. I'm sure some on this 
list do use that enlarger, and perhaps they can enlighten us.
	However, you might try calling the Ilford tech folks, who I have 
found quite responsive to questions on other subjects. They may be able 
to recommend appropriate dichro settings that correspond to 
black-and-white filter settings for their paper.  (Ilford also has a site 
on the Web and a support organization called Ilfopro.)
	Also, I believe that using a dichro color head for 
black-and-white multi-contrast paper requires an exposure adjustment as 
you change contrast settings. The beauty of the black-and-white VC heads, 
such as Saunders makes for its line, is that the exposure compensation is 
built in. Perhaps there is a module for your enlarger that does that. 
Again, perhaps a LUG expert will have that answer.
   For black and white work, I usually use a Leitz Focomat Ic, which 
predates yours of course, and an Omega D2 with a cold light head. I use 
Ilford or Kodak filters on both. For the Focomat, you can place a gel 
inside the head below the light source and above the condenser. For the 
Omega, I use a different set of filters made for use below the lens. The 
cold light presents its own set of VC problems, which I won't get into. 
But that aside, using the filters below the lens works just fine.

	By the way, what is the book?
