Heads Help!

Do you have any knowledge of what cam is in there now?
Can you indicate or estimate at what rpms you engine spends the largest percentage of time.or where its weak.
Ive only ever autocrossed twice and that was on grass so it doesnt count. Sure was a blast though.And I would love to participate more often but its just not feasible for me. The nearest track(concrete) is 1.5 hours away.I do watch it on tv or Utube whenever I can.I love watching you guys.
One thing I have noticed is that the engines seem to spend a very significant amount of time powering through the midrange. It also seems that the engines are often heavily throttled,down low; as in babied to prevent wheelspin/slides. And they only seem to spend milliseconds at high rpm. So it seems to me that the engines need a broad smooth mid-range more than anything.
What is your opinion on that assessment?

Is/are your gear ratios optimized?
