Default Holley Annular Question...?

Holley list# 9380 annular 850 DP

1) why or what are the benefits that it's a "square" jetted carb?

2) would it be of any benefit to remove the rear/secondary PV (it has two) and jet it smaller in the primary side and fatter in the secondary's ?

3) What are the benefits of this carb being "annular" vs any other 4150 ?

4) When testing w/a vacuum gauge, will the primary power valve automatically be the same as the secondary PV?

Thanks for any feedback > I called Holley and it was like talking to someone at McDonald's drive thru :roll:
