I also thought 42 seemed a little high. I'm going to start at 36 and go from there. I'll worry about the vacuum advance once I get the mechanical curve I want. My car has the adjustable vacuum advance so I can change it, I'll adjust it by driving it up a steep hill and see how it behaves.
I think my car does need a fair bit more timing because it seems to be out of where the powerband for this motor should be at the track. I get my best times and MPH by running it up to 6300+ rpms and it bogs out of the hole bad (2.0 60' times on sportsman pros) even with a 4000rpm launch, saying to me there's no torque down low.
