66 Dodge 383/325/290 any good for SS?

There were 2 different head castings for those 383's, I dont remember which casting number is which anymore, but one of them has a way better short turn radius on the intake port.
I used to do 383 bracket engines for a friend back in the '80's and he always went way faster with those heads with no work other than a race valve job.
