IMO with forced induction headwork is not that helpful. A cam might wake it up a bit, does Radix recomend a cam?

How about a set of 6L heads, that are cleaned up a bit (i agree with gmc, worked heads aren't needed) , bigger valves, and crank that boost up a lot. More boost will make more power than a set of heads will.
With a z06 cam, you are going to loose a lot of low end torque, the vette cam likes high rpm, will your charger keep making power up to 6500rpms?
I say the build the engine up as strong as possible, then boost the hell out of it. (the 6L heads will allow more boost), that should get you going.
Also, you might as well throw a 75shot NOS on it. hehehehe.
see ya,

I forgot about lowering the compression good point Farmtruc, find a cam with low in torque for a forced induction.

Thanks for the quick answers guys.
I need to do a deep research on cams and also thinking of a smaller pulley for the charger and a stall converter.
Once the moddifications start is addictive, somebody stop me please
