Ford 9" Ring Gear Bolts

I'm in the process of setting up my center section, and have a question about the ring gear bolts.
The spool and ring gear are set up for two sets of bolts, 7/16" and 1/2". Is there a recommendation for what bolts to use and a power level for needing both sets?
I bought my case and spool used from one guy, and the ring and pinion used from another. Each had only used the 7/16" bolts as evidenced by witness marks on the spool and threads on the ring gear.
Just wondering if there's a rule of thumb on how many/what bolts to use?
