I just reread the 1969 Hot Rod Engine article on the original, as well as perusing the specs and photos in it. The Ward's pics show an updated head porting, I would guess much inside is not the same as the original either. It kind of sounds like a way to make some "legal" blocks for some racing classes. Just as the new "Boss" engine has little in common with it's namesake, this one probably has little in common with the original. But the correct casting number on that block could be invaluable to some racers.
