Default 12:1 compression on pump gas and octane booster?

if i want to run at least 12:1 compression or higher on 91 octane...is it safer to add octane booster everytime i pump gas?

It'll be safe if you have adequate fuel and timing maps.

if you want to get by before tuning, use 1 gallon of toluene to 5 gallons of pump gas, and retard your timing a bit

I wonder how bad it'll be running 12.5:1 on 91 Octane. Someone in California is selling a fully built block w/ 12.5:1 88mm
