If you have any useful snippets of information please add it to the post.

A vacuum distributor is always preferred over a 009 as your engine will run better and be more efficiently. You can static time your vacuum distributor but you should then set it using a strobe light with the vacuum can and carburetor ends blocked off.
009 Distributor, the maximum advance MUST be between 28 and 32 degrees at 3000+ rpm. The 009 distributor is usually set at 3000+ rpm because it produces its maximum advance at 2600-2700rpm. Setting the maximum advance timing at 3000+ rpm ensures that it's "all in." If the engine pings/detonates at 32 degrees, then use 30 degrees or even 28. Never less than 28 degrees or the engine will be grossly under-advanced at high rpm.
