You can't race flowbenches.
What kind of flow did you get from the stock port? Your % increase?
Do you have another benchmark? Like, have you tested a box stock Edelbrock Victor or a Performer RPM on the same bench?
Having said that, 2.08/298/.500, is quite good. Edelbrock advertises the 2.20 Victor at 298 cfm @ .500 and the 2.14 RPM at 278 cfm @ .500
