    32 valve heads

    I recently came across the Arao Engineering website where they were touting increased torque and HP with their 32 valve heads for small blocks (and big blocks also). Does anyone have any experience with the small block application?

      no experience, just observations

      Interesting site. Notice, however, that even their own dyno runs show that the advantage doesn't even begin to come in until about 4000 rpm and the big difference is at the 5000 to 6000 rpm range. Which, of course, is to be expected because the need for better breathing is at high speed. So, it all comes down to how you intend to use the car... this is racing equipment, assuming they've made it bullet-proof.
