Spacer - not.
By Royce Peterson - 09/19/2002 9:56:55 AM; IP 63.87.74.238
A 1967 390GT engine should have an exhaust recirculation valve on the right manifold. The valve closes during cold start operation forcing all the right side exhaust through the intake manifold crossover until the engine warms up.

That part was replaced by a spacer for 1968 production. The spacer is undersized from the manifold. The resulting restriction forces hot air through the intake all the time. It also reduced warranty claims caused by sticking valves and rattling noises when the valves were open.

Another possible head casting number for 67 390GT is C7AE-L.
