 I didn't measure the carb side of the manifold. I measured the engine side of the manifold and the later one has the bigger openings. That manifold was from the 74 JH engine.

I guess I should measure the ports on the earlier 73 head and see if they match the manifold? Bigger holes on the manifold would be useless if the holes on the head are smaller, right?

Once again, thanks for the info!
