390-4V factory cast iron exhaust manifold set, both a correct right and left set of matching exhaust manifolds. The passenger side does require a spacer, which is not included. Indicate in the comments section if you want the early 1967 passenger side with C6OE-9428 casting or late 1967 and 1968 with C7OE-9430 casting.
* If concours or dates don't mean anything to you, we suggest the set with the late 1968 passenger side exhaust manifold, with doughnut chamfer, that does not require the spacer.
