To the best of my knowledge, the "old" style small blocks never came with aluminum heads until the 86 or so Vettes. There was an aluminum bow-tie head available over the counter as early as 1980, but never on a production vehicle.

I suspect you're looking for a set of L98 Corvette heads. The Corvette had aluminum, the Camaro had iron. Pretty good heads but might be hard to find. Started in 87 I think, up through the LT1 in 92 in the Vette. The LT1 heads won't work on the earlier blocks.
