Cast vs. Aluminum heads and bang for buck..

I think we may find the lower end aluminum heads becoming even more attractive vs iron, in the short term anyway. The Trick Flow heads look like they're shaking things up, so some may be getting out of the market, or may have to lower prices to attract buyers.
Assembled LA aluminum heads for $687.50, plus shipping. This from an email I received today from Mancini's:

We went to Edelbrock and made a run of cylinder heads without any logo's on the ends of the heads. They still have all the factory mounting holes in them. We also have ready to bolt on Magnum cylinder heads, since the Mopar R/T heads are no longer available.
Act now this great promo is limited to stock on hand
