I would guess Al heads and manifold would get more heat to the carb and tend to boil the fuel out more. As far as actual vapor lock in the pump and suction line, probably not much difference since that is down low... though exhaust and headers can have an impact.

A heat isolating gasket between the carb and manifold would help a lot with carb heat... as thick as you can fit.
