Another 87 octane/aluminum heads question

Almost 20 years ago I did a 451 Stoker with Edelbrock heads,and a 500 AFB.Compression ratio was 10.1 actual. I drove the car cross country on the Hot Rod Power Tour and as a test ran it over 1000 miles on 87 without pinging and plugs looked good.After that I would mix 87/91 or 93 depending on the part of the country.Only because of thinking I might hurt it.Drove that car 30,000 miles in 2 years. It's still running today.Aluminum heads with 10.1 should be no problem.Tune-able EFI should help too. Cam will be up to you.
