Yeah, it should be 10 deg advance. Did you disconnect the EST-bypass connector before you set the timing? If you did, maybe your balancer's mark is incorrect. Check out this message, I just wrote up how to check the balancer- and the guy already knew how. Oops.

the sticker on your hood should show the stock ignition timing.
