is 11.2:1 compression too much for 91 Octane

Okay, I have the cam specs:
Grind: 250/263H13
Lobe Lift: Intake: 0.360 (intake and exhaust)
Rocker ratio: 1.5 (intake and exhaust)
Valve lift: 0.540 (intake and exhaust)
Adv Duration: 307 (intake) 318 (exhaust)
[email protected]: 250 (intake) 263 (exhaust)
Lobe centreline: 110 (intake) 116 (exhaust)
Lobe separation: 113
Degree intake lobe to: 110
Spring pressure: 135 seat 325 open

Does this look like it would be able to run 11.2:1 on 91 octane?
