As said, we all need a cam manufacturer and part number, not just ".480 cam"; there are several different duration cams with .480" lift, and some will be much better than others at not damaging the low end torque too much. (I.e., not making it doggy...)
Are you racing this car on the strip? Or just cruising? Or??? That will say how the engine torque band should be set up.
And I'd be preparing to do some milling and chamber volume measuring on those heads.
