are you asking what is the most compression you can get out of a stock head?
you can run as high octane as you want, but like stated above, you will waste your money.

Octane is required for suppressing detonation.The higher the compression the more octane you'll need.Whats the lowest octane i would run in a stock or mild 250r,premium;) Theres lots of good info online about this subject
