Edelbrock/cast head flow numbers?

Thanks for the Edelbrock info. Also, thanks for the info on the 308 heads. I had head that before, but just wanted to double check. After about 4 hours of searching, found this link-
http://www.mopar1.us/cylhead.html
It has flow numbers and sources for many different Mopar heads. I guess I'll just keep searching for a pair of the 308s and bring them to my builder. It's sad to see my set of heads near the bottom!! I'll get cracking on these.
