Edelbrock Heads Sound Like They're Terrible

IMO the RPM air gaps are over priced as well. Have had 2 of them with horrible core shift. One of them the divider on the duel plane was so far off center that a holley 650 butterflies hit it. Would only open 1/4 throttle. And the ports are so far off from a gasket that it is a joke. The Chinese versions are a lot closer OOTB and that is sad for an item that is almost 1/2 the $
