What is the deal with Gen 2 Hemi blocks?

I think World Products was the most recent company casting the Mopar Performance blocks. Have you contacted them directly for an answer? Mopar always does this, leaving parts on backorder without saying if they are actually going to make any more or not. Also, are Koleno, and Indy cast iron blocks an option, or even still available. Not sure exactly what you are looking for, which style.
