Aluminum block/heads

I've been going round & round with my son on his Charger build. He keeps upping the ante on his motor goals. Ideally I'm now looking for an aluminum 440 based block. - Would prefer a Keith Black but would definitely consider a World block, Indy, and others. Also looking for a set of B-1 heads but are still on the fence and still considering a set of Victor Max-Wedge. I know these parts aren't cheap. Any responses or leads would be greatly appreciated. We're located in Nebraska. Thanks.

ditto on the alum block.
