I just wanted to know if anyone knows any reason why I might not be able to use cast iron vortec cylinder heads on my original 327 block. I realize that I would have to use a vortec style intake manifold and use center bolt valve covers, but is there any thing else that might not be compatable?
Just double check the cc of the heads your replacing. Vortecs are 64cc which I think your heads should be too, then its a direct swap. As for the rockers, another way around it is to have them drilled and tapped for screw-in studs and guide plates.
