I went with the stealth heads for my build as well. I'm still not sure if it was the right choice, but it's done. I didn't want to have to deal with spending the $ shipping a set of spare stock heads out to a trusted head porter, having him port and rebuild the heads and shipping them back. Probably would have spent the same in the end either way. I'm kind of wondering whether I should have just saved my money and went with a set of e-victors instead, but they may have been a little overkill. At the end of the day, there's more than one way to skin a cat so do it however you want. I agree, not everyone needs aluminum heads, but these days 500hp is as impressive as 400hp was 10 years ago, so everyone wants to keep up with the times. And for those #'s, a set of unported stock valve heads won't do it.
