Thanks for the tip. Too rich part-throttle cruise is my whole problem! But "up top" won't the secondaries be coming in too, and I can tune them leaner to compensate?

The Eddie RPM has a gap in the divider, not a 100% dual-plane. What would you recommend for a single-plane then? I'll probably put on the aluminum heads this winter (293.5 cfm at .600-up and also breathe better at lower lifts).
