When we were discussing a new big cube build, this topic came up and we spent quite a bit of time discussing it. For a high-end NA street/strip engine, the performance difference between hemi and wedge is almost non-existent now with the big B1 and Predator products. Hemi is still a bit more expensive. The tie breakers for me? Resale value and "wow" factor. As somebody said, "Hemi" may just be a word, but it's a word that always draws a crowd when the hood comes off, and its worth another $5-$10K in resale value at the engine or car level when it's time to sell. Hemi's definitely hold value better than wedges.

I came across a used set of Millennium heads for a good price, so the cost difference was eliminated. I'm building a hemi!
