So running 110 octane racing gas (theoretically, I won't be doing that at this time) wouldn't require a timing adjustment on an engine that was tuned to run on 91/93?

If thats the case maybe I'll bite the bullet and run it on an octane that I know to be higher than what he would have been running it on until I become familiar with the engine (mix 91/93 with racing fuel). Then I could back the octane down to where it isn't wasted. Any issues with this plan?

Thanks for the quick replies, I appreciate the help.
