| RE: 390 GT Heads |

Yup.
The heads are C7AE-A. Or C6AE-U. Or C6AE-R.
If it's a California-origin car, they're also drilled for Thermactor emissions.
The exhaust manifolds are pretty simple, but I'll have to look them up - when I get a chance. The number is the same with the '67 Fairlane, Mustang, Comet, or Cougar, as the only oddball FE Fairlane/Comet manifold was 1966, as it wasn't compatible with the 1967 Mustang/Cougar and was thus redesigned for 1967. Redesigned, yes, but it still offered the crappy breathing characteristics GT owners came to expect in the 1966 model.
If the intake has an "S" on the #1 runner, has four barrels, and an appropriate date code, it's correct for your 390 GT motor, and a buncha other FE motors that year. The "S" intake is an "equal runner emissions" intake and, though it sits 3/4" taller than the "T"-type "low-riser emissions" intake of that year, it offers no extra performance. The "S" intake is, however, the cleanest running and smoothest idling intake that the FE ever got (JMO).
B.T.W.: C6AE-R heads are the good "cheater" heads and can be turned into CJ+ heads with nearly no effort.
Unlike Mr F (who only states fact), this is just my opinion,
