That looks almost 10 degrees advance and prior posts on here by engine builders say that would be too much advance with a stock cdi and you could deto in the higher rpms...you can get away with more advance with an msd enhancer...that small dot on each side of the stator plate center mark is 5 degrees and would be much safer...I would say you will feel a little bit more low end snap compared to stock...and use higher octane pump gas for advance timing also.
