I have a B engine, .060 over, lion 6.0 head, Holley 94, B cam and it idles like a kitten purrs. A new, tight engine can idle rough, spark gap makes a big difference.. I think the suggestions Mike makes are probably more likely to find the source than replacing the head. Lion heads are generally smooth running.
