Guys:
I'm actually about to start building another 240Z, and I'm reading around now doing research on here. I think I'm going to go with a streetable, ITB L24 with 215-230WHP as a goal. Like the OP, I very much appreciate that higher rev range. I think that many of you might be missing the point of the higher revs... at least MY point with it.
I have been blessed with the job of test driving Porsches and writing about them (Excellence Magazine - World's Largest Porsche Mag). Testing numerous different 911s in solid 3 day sessions on rural roads (attacking the roads cannot be overstated), I've come to appreciate the higher revving cars (ala 2011 GT3-RS) because you can stay in 2nd gear (still on throttle) into the braking zone of the next tight turn instead of having to grab 3rd for a blip of the throttle before braking and downshifting. When figuring in shifting and such, the car that can stay on the power longer and without having to shift is faster. So this is what I'm researching. Yes, I'm reading all that I can on here, but since my desires seem to be on point with that of the OP, please feel free to tell me what you'd suggest as far as heads, CR, cam, etc.
Thanks!
