Your right, some will spend hours getting it to the degree, only to lose a couple? LOL. Forget the degree wheel. Put number 1 cylinder on TDC, and then put a straight edge on the exhaust/intake lifters. They should be bevel, no gap. If there is, then move the cam in the correct direction. Use a decent chain set (edelbrock is decent to me - 75 bucks) and never look back.
