EQ318B Magnum heads discontinued ?

I spoke with Stephan Richards from A&A yesterday about the CH318B Magnum Head with LA intake bolt pattern and he stated that there is no future casting date for this head. He does not know if and when they will be available and can not give an answer as to why. The CH318A is still available, so that only leaves 2 choices for intakes, Eldebrock And the Chinese knock off!
