Not in the market. If I'm buying cylinder heads, I'm looking for aluminum.

First Guess: You'll be lucky to get them for $800 EACH, never mind for the pair. They will likely cost more than the common aluminum heads.

The likely way to get a reasonable price on them will be to source them out of China or India. And then the consumer have to remachine the entire thing, like guys are doing with bottom-feeder crankshafts, and bottom-feeder cylinder heads from the existing manufacturers.

But, hey--I've been wrong before. I think the best we could hope for is to convince the folks in Vegas to have the down-under foundry make them (Toowoomba Metal Tech). They do a reasonable job with the Chevy heads; of course the Chevy heads sell in amazing quantity, the tooling/foundry cost can be amortized over a much-larger production run.
