It might be and it might not be. Have you taken off that cam's valve events? If not, you can't make a sound judgement. Mine was best installed 4° advanced.
Retarding or advancing a cam type judgement has to be based with all the engine/drive train parts in mind. Retarding may be the way to go, or advancing may be the way to go - but you have to have enough information to base the decision on, just don't decide to advance or retard based on anything but the combination your going to use and solid recommndations from people in the know - like people that have run the combo or some of our better known engine builders (if you can get them to cough up some advice).
