All 70-72 O.A.I. bases are the same. There were two different breather arrangements. The W-30 cars and all 455 4 speed cars with W-25 used the dual breathers with a PCV valve in the intake. All small block cars (incl W-31s) and 455 AT W-25 cars used a single breather, PCV in the valve cover, and a rubber plug in the extra air cleaner hole.
