91/93 octane should be fine, if you hear any pinging,try adding some 100 octane AV gas....
My old 351-W with iron heads and 10.6 to 1 compression ran fine on 93 octane...Once when running low on fuel,all I could get was 89 octane,it ran fine except slight pinging when acceleration in high gear to pass another car on the highway,as soon as I could fine 93 octane, finished filling it up with 93 and was good to go.......
