you should run the lowest octane you can in ANY combusion engine without detonation. the higher the octane, the harder to burn. in a low compression this results in an incomplete burn and equivalent if not worse performance. if you really want to run it and see an improvement mill the piss out of your cylinder head until you get a compression ratio of about 16-1 and then youll have a fun ride. otherwise, dont bother.
