All it takes is money! That is not a cheap motor and the return over an AFR headed motor would not be that big IMO. Car Craft featured a motor that used all out of the box, off the shelf part that made 700hp. It was a stroker windsor built by S.A.M. School of Automotive Machining. CHI heads are great, but I have not seen any of them at the track. Yates and Brodix seems to be the heads of choice.

Yates, Brodix and Ford Motorsport heads have lot bigger ports, good for the racetrack but not good on the sreet. They actualy only recomend them for racing or realy big cubic inches. By the way the CHI heads were not off the shelf, with the bigger bore, the valves are too shrouded and the combustion chambers were modified despite what the article says, the ports and manifold do require port matching.

I was not talking about the engine masters build. They did an AFR headed motor. The motor was reported to be all untouched catalog parts, no massaging, no custom. I wish I still had the issue. I think it cost about $7k to reproduce including block machining and balancing. It would be hard to get that kind of n/a power for any less.

The Car Craft article you are talking about was a big block chev with AFR heads. The School of Automotve Machinists used Modified CHI heads. Have a look at the pictures and you can see the head work.
