Thing with the headers and intake is that it sounds like they were used to spread out any torque gains as widely as possible. So there is probably power available with the natural caveat of the narrower powerband.

As it stands the rev limit is putting the mean piston speed ~4200 ft/min. If they over-built the bottom anticipating 8000+ rpm, then cams plus tuning the full torque peak to ~6500 should give some very nice top-end power gains.

I think this motor with a more specifically-tuned rev range will put out ~170+ lb-ft.
