Anybody know the 7 digit IH part number for the Inconel Exhaust valves, or are they only identifiable by the dimple? I tore down 6 pairs of heads recently and one set that was apparently rebuilt in 97 had 1811 191 C3 Exhaust valves with the dimple. They look to be salvageable.
As a side note. 67% or Eight out of Twelve heads were cracked. Five out of Six Left hand heads were cracked, or 83% cracked on the drivers side.
I'm really thinking about Evans WC...

If they have the dimple, they should be from an IDI Turbo (inconel). I bought new exhaust valves from Hypermax that are Inconel and intended for the turbo application.
I don't have the IH part #
