Intake Manifold

Hi, I am after a 1962 Intake manifold 4 BBL for a 394 Skyrocket engine. The engine has a prefix "G" so it is the high compression engine. It should have a 4 bbl carb and intake but has had a 2 bbl put on it. I have found one on ebay. See link below. The seller is not sure what year it is off. It has the casting number 580677. It hass a number of "117D" or that is what it looks like. Can someone please help. I need to make sure it will go on my 394.

The casting #580877 is correct for '61, '62 Full size Olds, but the # that you have posted is for a '63, '64 394 engine and will work as well as the previous Intake mentioned earlier.

The only real difference is the '63, '64 Intakes have a vaccumm port in the rear of the manifold

What about the choke heater? There is no hole in the right side exhaust port to connect the air tube to the choke. I am assuming that means there is no heater tube in the manifold, either.
