Exhaust manifolds for 371

What you have there is one 1957 head (#14) and one 1958 head (#16).
I don't know if these heads both had the same size chambers.
I know there was a compression difference between 1957 (9.5 to 1) and 1958 (10 to 1).
To me, it would be important to CC the chambers on both heads to ensure that all eight cylinders have the same compression ratio.
