Take the combos in the Ryan web site for what they are. Basic ideas, without specific details, drawn for the most part from old hot rod mag articles that are famous for missing critical details and spec errors (editing errors).
That combo (the real combo) probabily had more actual compression. You'd want to maximise the net valve lift to take advantage of the AFR heads with that mild short duration cam. (use 1.6:1 or higher rockers) you'd want to run as close to 10:1 actual compression unless you are restricted to junk 87 octane fuel.
You might want to start with a 600cfm carb body but modify it for more airflow while keeping the small venturii size for good fuel mileage etc. Engines are all about airflow.
