The 250 dyno tests we are going to be conducting are going to be using the same heads for that as well, so we'll see if that shows any additional results to support that or not. Also, for many years, a lot of people for some reason or another, have the misconception that you get a magical or phenomenal increase in power with only a very tiny increase in compression, in this case, hardly 1 full point. So, its possible that this performance gain was or could be contributed to something you had absolutely nothing to do with at all. Unless the head swap was done at the track, the same day, under the same track and atmospheric conditions, its possible that those variables had more to do with the gains seen, than the head itself, so consider those possiblities as the reason. Irregardless, most people look to dyno results as being the absolute authority for debates such as this, because a dyno is a more controlled environment, and a track has too many variables to consider. But, we'll see how a 250 reacts with that same head on it.
