Lots of variables, but our club dyno days seems to show the as-cast D-port Edelbrocks making a little more horsepower than the Kaufman's. We also saw that stepping up to even the first level of porting with either head really kicks up the horsepower and levels the playing field between the two where it's more of a coin flip on which head comes out on top.
