It's been a while but I thought the cams with different exhaust lobes were only used with the early heads?
In any case, I wonder if a lot of what you're seeing could be due to overlap. Low compression and low vacuum at idle would fit with that. And a lot of overlap can give an EGR effect that reduces the engine's tendency to knock.
Regardless, I think you need more boost. ;^)
