exhaust manifold

[my62cat]

Are the exhaust manifolds on a 1962 Pontiac Catalina with 389 the same for single or dual exhaust?

Wallace Racing shows only one part number for 62

i don't understand the chart. it shows a few different casting numbers for 62, my car originally came with single exhaust ,so I should be able to use a dual exhaust setup and it would bolt up?

I have a 1964 Catalina with a 389, and a 1972 Lemans with a 400. They both had single exhaust when I bought them. I went to a local muffler shop and had them change both to dual exhaust. The manifolds are the same for either dual or single exhaust, and didn't have to be changed. The tail pipe and mufflers after the manifold have to be changed.

Unless you have a Super Duty, it shows only one number for left and right for a 389.

This is what I'm working on and I'm sure I will have more questions as the project goes on
