David Vizard, Uncle Tony's garage, Unity motorsport. Mission impossible Dodge 302 Head porting

I tried to get through every page, but i had to skip a few, a lot of talk about the 302 heads and how much better they are, has anybody run a set of 302s and then a set of the 675s and know how much differance it made, like ETs at the track? I have personally done this experiment. And the 302s are not better.
