It is my understanding the Dunn heads flow better than the Birmal heads. If that is the case than my ported Birmal heads and recut valves are, performance wise, better than the Dunn heads. So if this be true all stock Dunn heads give you is strutting power. If I'm wrong then chime in.

Sorry if I stole this thread.
