If you have to have Edelbrock heads, there is a guy on the facebook group FE Fanatics that has 2 or 3 sets of unused heads he is selling. Seems like summertime is the answer on when Edelbrock plans on getting back to producing the FE heads. There is a bunch of internet chatter about what the situation is, but what I'm understanding from reading everything is they have limited foundry production right now because of their move, and obviously the FE isn't their top priority.
