340 Six Pack Setup

Can you give me any history on intake manifold? Original Chrysler part or aftermarket Edelbrock? Milled in any way? Condition including threads? Pictures of head mating surfaces would help. I could not find that info on FEBO forum. Thank you.
Please PM me here and I’ll give you my cell. I can send pictures. Intake is original Chrysler with part number. It has been cleaned and checked by my local engine shop. It’s is ready to paint and install. It has never been cut.
