The point I want to make is that the Victor head is worth the investment. They made 1.7 hp/cu in, which on a 408/416 is around 700 hp. And the best part is you can bolt them on and go. All that was done to ours was a valve job and clean up the tool marks. Everything is available now to complete the build. I admit it's not cheap, but it's a lot more affordable than you think.
