I don't agree with the overall results. IMHO a Apache, ported or not is better suited to a 440 and above.
I've dealt with a racer in direct compeition to Alcharger. He ran less cylinder head (eagle) and was still faster over all and also less CI.
An effcient head is what we build for. Different styles work for different aplications.
A lot of what you're saying makes sense, Alex. You've probably forgotten more than I know about the these new hemis. But I still can't get around this: why would Chrysler spend so much money in R&D to design a new head for the 392 if the older 5.7,6.1 or eagle would have made more power? If it's a low end tq issue, that could have easily been reduced electronically. I can't help but think the engineers wouldn't have done it if the port velocity was that bad. They still did despite the low compression,small cammed,low stalled, and heavy application.
I believe that was infernalAl who did the head swap on his stroker; eagle to apache who picked something like 40 HP to the tires.
