Morgan,
Did you originally purchase the Edelbrock heads raw without valves/springs or did they come with them and someone just ported them for you?
...If you used the Edelbrock valves/springs that came with the heads, I have something to share with you after experiencing the exact same type of failure with my former .640 lift cam
