No, the heads are fantastical. They're the whole reason I've been butting my head against this cam sensor for a year. This dyno session was to work out the issues with the cam sensor. The timing up top was pretty soft.

The heads are ported, and they look great. I'm starting to see a few other things I left off the list, like the EL header, multi-angle valve job... You'll have to excuse me, since the list was off the top of my head.
An intake manifold would likely help some, but that wouldn't get the 350-450hp I'd like. There's an 1100HP EVO II out there that's taking my lunch money.
This video was the 4th pull we ever did, and you can see that it holds 700hp. The timing was fairly conservative here as well, considering the fuel. By the time we left for the mile, it was holding 700 to 8K, and we were prepared to turn it up from there.
