questions on timing an engine

When it was dynoed the guy didnt mess with the timing he left it where i have it at. And i get the point now and to better answer 67dart273 when i set the initial timing at 10 degrees then rev up to 3000 rpm and pull it back to 35 degrees and let go of the throttle and check the initial again it reads 8 degrees on my timing light, so does that mean i have a long curve or fast curve?
