My guess, you flow the heads on a different bench with a more correct bore size (4.030) it will change some things. If the air attaches to the bore adapter properly, enlarging the bore on a really refined port will make it go turbulent at or around .500 lift.
There's also not very much bowl in the OOTB heads to do a nice Venturi with 2.02 valve size. What matters most...if the engine makes good power for the parts involved, and the car runs numbers...then it's good. Throw the flow sheet in the trash.
