I will assume you have the vacuum advance plugged off. I am not sure of your timing light but it sounds correct. YES, you need to advance your base timing to get the additional 2 degrees of total timing. Some distributors have a limit on the amount of centrifugal advance. Different springs may allow more timing but also may come in sooner.
Let us know if you get it where you want.

Any other ideas? I am also wanting to put some different weights and springs to help performance mainly at low rpm. I am reading that I should get the total timing set to 34-38 and forget about the base timing.

Still reading up on this and found a couple links that might help others looking for a better grasp on the timing of a sbc.
