Yup. They're the same. |

FE non-racing heads from mid-1958 thru the end of 1965 are all basically identical. Early 1958 heads also have the same runners, but the chambers are machined.
The C6AE-R and CJ heads retained these runners, with the exception of Thermactor emissions bosses which were added (and sometimes drilled) in the roof of the exhaust runner. The C6AE-R (as well as some industrial/truck/marine heads) got an additional AR lip, but that's a different story.
Otherwise 1966 was a big-change year for the FE head, as emissions regulations forced efficient "high-velocity" runners (also known as "small runners") into most of the FE's being produced from then-on.
