I just talked to my mechanic about vacuum advance today. In my case I am using the original 18rgu electronic dizzy so it may/maynot apply to your case.
He said that vacuum adv is mainly for idle/off-idle and mainly used in autos.
Also the vacuum needs to get be attached to each cylinder not just one otherwise it will screw your timing as each individual cylinder fires, making the vacuum inconsistent(assuming you have the std four separate chamber manifold)
So as far as I understand just rely on you mechanical adv.
