I've made quite a few color prints using the illumination provided by the light passing through a color transparency projected onto the model with a Hasselbad PCP-80 Projector, and every one required additional cyan filtration, due to the imbalance of the light (all photographed on AgfaColor 400, balanced for daylight).
I wonder about the color balance of your negatives: What was the color temperature of the light used for their exposure (approximately), and what was the "balance" of the negative film?
I've just worked with Fuji Crystal Archive, and it does take less filtration - both magenta and yellow - than my "old standby" Ilfocolor.
It may be that you will need to decrease the color temperature of the exposure using yellow/ orange filtration.
Wait..... After "proof reading" this ....
You say that your prints have a "cyan cast"? To compensate, you would have to ADD 5-10cc of CYAN, not magenta. Remember this is a negative printing process... you must ADD to the color filtration to remove the same excess color from the print.
