Yea, Jim, Edelbrock is on your side all right...More like you are on Edelbrock's side copying a proven design GM developed 40 years ago. It was the port design and the availability of the exhaust or headers to bolt up as to why Edelbrock designed them. Maybe you should have read that article in HPP about 10 years back.
And for the sake of correctness for anyone reading this, the Edelbrocks(RPM) still have the round port design which still has limited exhaust applications....
