I just looked at the guide for 1965. The replacement head does have its own column.
However, once again, Jimmy was told, at Bowling Green, on Memorial Day weekend, that the base class of the car was the same as if it had iron heads, regardless of how much extra HP was put on the replacement heads. So the current combination can no longer be run in SS/B.
