Holley 4150HP question

I purchased a 4150HP Holley 950 double pumper and there are no vacuum ports. Is this correct? Do you go without vacuum advance or hook up elsewhere?

These Are Race Oriented Carbs,the Reason You Wont Have Vacuum Ports....downlegged Boosters/no Choke Horn Designed More For Racing Almost Impractable For Street Use.also Its Alot Of Cfm For Street Use Unless You Have A Big Inch Engine. If Your Running A Mild Street Engine It Is Better With Vacuum Advance Distributor And Smaller Cfm.

Just drill & tap a 1/8"npt hole into the manifold behind the carb base and fit a barb for the advance.
