You can probably run up to 14* but may have to run premium fuel. Every degree of timing will be worth a bit if hp. Just pay close attention to spark knock. If you get to the point where there is spark knock then back it off 2* and you should be good. You can check for spark knock by loading the engine. For instance try going up a hill in 4th gear at about 25 mph give or take. This will load the engine when spark knock is most likely to occure
