Just reread an old Mopar Muscle magazine article from 2003. They took a stock stroke 340, bolted on W9 heads that were pretty much stock( minor work, they went 280@.600) and with a 260@50 roller made 602 horse at 7000rpm I don't know how much better that head is than the procomp cnc I am thinking about, but it can't be much better, if it is at all
