Ok, this is news to me. What do I have to do to "correct" my new Edelbrock heads?

Sorry to hear about your misfortune.

Edelbrock heads are known to have tight valve guide to valve stem clearances. They really should be checked and corrected before installing. Also a good idea to have the valve job gone over too.
