It all depends on how hard you want to run. I have 10.5:1 with iron heads and get by with 91 octane. If I was going to run hard 93 octane or higher would be in the car. Having said that, a guy I really respect because of his knowledge and background said 9.5:1 is the max he could recommend for 91 octane.
