Extreme ported 3500 heads are mythical beasts. To put it in basic terms, the intake port opening at the gasket is smaller than the size of the intake valve, or about the size of the seat throat area.
That leaves you with the 3400 heads for all out boost performance. 3500 is still great for boost because they flow well out of the box but they just don't have the potential at the moment. Hard to say when they will, since its been 12 months since they should have been available. It takes a lot of porting for the 3400 heads to outflow the 3500 (street/strip is close, race/boost porting does it). Flowing heads without the manifolds is quite different than comparing with everthing attached.
For a supercharger cam, I only have 1. Its posted on my site and you can see with a stock motor that it takes away power compared to a stock cam until about 5500 RPM. Then it kicks ass. Someday I will have the rest of the simulations done and you can make more comparisons "on paper". I spent a lot of time trying different lobes and centerlines and lobe seperations. That cam is the only one that was close. On a modded motor its better than the stock engine shows so thats a plus
You mentioned a high lift cam but really, you don't need it. The 3400 and 3500 heads both flow very well for intake/exhaust ratio. The 3500 is nearly 1:1 flow it with the manifolds on in stock form. I would stick with the stock cam unless you want to rev it past 5500, then I only have one other option.
