I have been a believer that heads make the engine a long time now. When you see an engine with excellent heads make power all the way to 8K rpm with duration in the 230 @ 0.050" range, you realize that radical cams are a crutch for poor flowing heads. I'm not saying you could not have made more power with more cam. However with good heads more cam gives up low end for top end, and usually your giving up way more on the bottom than what you are gaining on the top. For the street I would prefer the bottom end. Good heads and mild cam makes for a great street engine.
