Maybe, just maybe you should watch some David Vizard and Unity Motorsports Garage videos. There are a bunch of others also that speak to ported or manifold vacuum. The short speech; manifold vacuum with an adjustable vacuum advance so you can dial it in.
I have. I do not put Vizard on a pedestal and regard him as the all knowing, all encompassing wonder man that some people do. David is a smart guy for sure but he speaks in absolutes and there are plenty of ways to get things done.
