Who's used SBM Victor heads?

I'm looking to buy a set of Victor heads for my build and I'm trying to get a handle on the rocker arm situation. I read that these heads use bb mopar rockers. But do they use bb shafts and spacers also?

I want to use Comp Cams pro magnum steel roller rocker arms. Can someone help me here?

Thanks
Call Hughes they can get u on the way.
