Are the Hemi exhaust manifolds I have "right" for my 69 Charger?

[Daytona Jim]

I have a pair of exhaust manifolds that came with my project 69 Charger. The right side casting number is 2780518 with a casting date of 2/10/66. The manifold is not drilled for choke tube. The left side casting number is 2780611 with a casting date not readable. My cars build date is December of 1968. Thanks for any information. Jim

The right side not being drilled for the heat tube may be a reproduction. I'm not sure what dates were available on the reproduction parts. I have a reproduction right side Hemi manifold that I can look at tomorrow.

2780611 is 66-70
2780518 are you sure its not 2780508?
