Very interested in this. I've bought the S&S 865 kit, cam and clutch. Also have Powertronic and a full quality exhaust by a local company here in Tasmania (Verex). I'd be ok with the same engine characteristics, just turned up to 11. So like others wondering about the difference between just doing the bolt on stuff (well, there's the machining for the 865) vs that plus head work. By what Revelry in Sydney said about the street bike they did for the Queensland customer (stock head) it may suit me. (they charge A$3000 for a worked head!).
Great thread and can't wait to hear results.
