mike or ss will using higher octane than 91 benefit me at all or could i use like 105 or 110 lead or no lead , since i don't have cats, but will it help out a little in performance? or just a waste of money?

Unless you increase your timing accordingly using 105 or 110 is a waste.

3 degrees advance and CA 91 oct fuel, you might want to put some high octane in there considering the CA fuel quality.

Also watch your use of leaded fuel with your stock O2 sensors, it will shorten their life significantly.
