My 422 smallblock build

Just read that Hotrod article and I didnt understand a few things...
1) did it say the builder had to tube his W2 pushrod holes then opened up the intake ports beyond that ? He must have different W2s than the sets I have had over the years ! Or ported them out to Landy Prostock proportions !

2) Where are the flow numbers ? Did I miss that ?

3) Why cant I find these mystical deals like 99$ Geardrives ? Lol
