Ported vacuum is ,I would say,in most all cases the way to go if.. its a street driven car (which most of our cars are), as you only need vacuum advance at steady speed cruising for economy and engine life.Also if you you have too much vac advance at idle you are probably nor going to have enough mechanical advance at WOT,assuming that now that you have so much idle advance that you dicked with everything there is to adjust to get it to idle anyway half decently.Even quite an agressive cam with the correct timing combinations can run pretty smoothly.
