9 Basilisks would almost cost you almost 1000 points. So assuming you're playing a 2000 point game I'd say 9 is too much and you're kind of gimping yourself. I mean ether you're taking multiple spearhead detachments of which most tournament rules only allow 3 or your stuffing them into 1 spearhead detachment in which case you're only getting 1 cp point. Or you're using them in another detachment in which case you don't have many points to fill that detachment out.
All of this of course is a guess on my part because I don't know the specifics about how you're playing.
Point limit?
Detachment limit?
Tournament rules or casual play?

I play Death korps of Krieg myself and while I don't use Basilisks I do use 3 earthshaker cannons which are basically the same thing only they don't move and 3 seems to be enough for me.

Uh, no, that's not Warhammer. Not even the dwarfs are running that kind of tech.
