Well, I'm sure you would have to look at the flow at every 0.1" increment of valve opening to compare the heads for a milder lower lift cam.

I was thinking 500-550 hp out of that engine with my milder cam and a very flat torque curve. Am I wrong?

I like to get my power by the best flowing heads and keep the cam more tame, so I can have the flat torque curve. I want my peak Hp by 6000 rpm at the most. 5500 at the least.

So are you saying that for such an engine the CHI heads would not be any better than trick flow or AFR heads? Or at least not enough improvement to justify the cost?

I wasn't wanting to hijack your thread, but if you are wanting to toss raw meet to the Cobra guys, I do think a milder Clevor would interest a bigger number of us. I admit I am talking way too mild for many. Call my idea the extreme of the mild side and the engine you just built as the extreme on the wild side (at least for a street Cobra), and that should about cover it, as anything could be built between the two.
