Have never run any radical cam just basically stock so for me ported vac has always worked just fine. Still only running an explorer cam which is basically a truck cam so ported vac still works fine for me.
My engine came with a B303 cam installed which is as close to a performance or radical cam as it was ever going to be but didn't like it because it wouldn't idle smooth so I swapped that out for the explorer cam. I never liked a rough idle in a street car.
