Thats enough to change your compression ratio and seriously effect your AFR. Did/do you run a wideband?

hey excessive did you record your runs at the track on HP tuner?
if so take a look back and see if there was any diff between first run and second, you said your second run was slower...
i feel your pain
, but time and a new motor will heal all your wounds.
did you get my email yesterday ??

I don't know about the flow numbers...did not get a sheet on the new heads. I did bump compression slightly by 0.5 +/- .1. I did not think that would make that much difference, but did not run the car at the track without my HPTuners hooked up. I don't have a wideband was just comparing the narrow O2 runs from before and after the head swap and they were basically unchanged only slightly richer (which was puzzling).
