I prefer Edelbrock heads. Great company, good owner and they work pretty good too.

Check on the quality.
I know the e/brocks come with helicoils in the exhaust stud holes - not sure about spark plug holes. Apart from the obvious flow/performance its those little touches that most people miss.

I'm thinking there's a huge difference in airflow between these two heads. (In favor of the RPM heads)
