Nice one - thanks for the advice. There's a great book by Richard Holdener I have been reading called Xtreme B-series honda engines and it's sparked a few ideas. Cams are appealing as once they are done there's nothing visibly different about the motor.

I hadn't considered the rough idle issue as I thought that was largely avoided with VTEC and Stage 1 cams - most of the marketing materials about mild cams seems to indicate that the b16 would keep the factory idle. Is this marketing hype?
