I'm not a racer and I tend toward originality in my cars. I've found the 461s, 462s, etc are good dependable heads and I have had them completely rebuilt for less than $300.

I believe that for daily street use the aftermarket heads are overkill and a waste of money.
That may be fine for your car. However Hopper has made it clear he is after high performance in his ride. IMO, the 60's and 70's head technology is a bit outdated and the new design heads improve performanc and cylinder head cooling dramatically. If someone were building a "correct" restoration, the 461's may indeed be correct, but that is not the case on Hopper's engine.....
