I do not feel that making aluminum heads legal will save the racers any money because head porters will still port the new castings thin like the oem castings in a search for even more horsepower and everyone will be back where they started.

Dwydendorf; the new casting have thicker deck surfaces and are made of better material, also they are new, not 30 or 40 years old. There is an incentive to running the older heads; its' called HP . There is HP placed on all motors that have replacement heads. With the newer heads the head porters have more than enough material to work with because the heads are cast with the purpose of being ported. As far as the expense; like I said before the aluminum heads cost more to start with, but you will save money in the long run on repairs and up keep. As I stated I have one of each so believe me when I say I know what the cost of both are.
