as for aluminum heads....they just lower weight and dissipate heat better, correct?

Yes, but the new alloy head offerings get better and better in terms of flow.
The weight savings of just small block heads is really inconsequential to whole equation. Cobras are roughly 2,500 lbs, so 25-30 lbs (or whatever) is a rounding error.
In fact, most people could start running and/or go to the gym and lose 25-30 lbs and achieve the same weight savings as the alloy heads, plus they'll become healthier humans, which shouldn't be "discounted."
