I'm looking forward to this also! I have the trick flow heads and run a solid cam as stated in my signature. My first run I wanted to take it easy down the track but spun hard at the line and short shifted at 6300, ran 11.95 at 112. Second run spun again but only made it just past second gear before I crashed. I have no doubt I could get deep in the 11's with those heads. I did notice I could use way more gear than the 3:91's out back
