Vortec heads on 3892657 small block 327?

[Spassmacher]

I'm trying to build my 327 up a little and have heard a lot of great things about vortec heads. I know that the camel hump heads are typically overrated, so I'm looking into vortec, but I wasn't sure what I should be looking for. Will they bolt on to my 327? I've got a 650 cfm Edelbrock carb and know that I have to get an intake manifold that is appropriate for the heads I end up with. The machine work, balance job, and cam work is being done by a pro, so I don't really have any numbers there. Mostly just concerned with mounting the vortec heads to my '67 327 block, and finding out what that would mean for the rest of my build. Thanks guys!
