Here in Kansas some dove heads, let alone even a 460 is very rare. The doves I find on the net are around 500 bones. I can get a pair of Super cobra jet heads for about 1000 dollars but do I have to get a special intake and headers for the SCJ??

What rpms to the SCJ heads/intake/header combo make thier power?
good for drag racing????

If you are talking about iron CJs, the head can support 9000 rpm on a 470ish motor, and near 900 horse. With no power adders. But, to do that will take a head that is worked over pretty good.
