I believe you mentioned it was a '64 bird. This motor has 2-bolt motor mount bosses cast into the block, which is one complication, because all '65-later blocks have 4-bolt bosses to attach the motor mounts to the block.
The 1964 heads are nice in that they are the large-runner variety, much like the CJ head. The problem is the 8-bolt vertical exhaust pattern of the early heads. This is tough to retrofit to Fairlanes and Mustangs because the lower 4 exhaust manifold bolts on each head are REALLY REALLY tough to access when installing headers. Log manifolds won't even fit in a Mustang/Fairlane.
In 1966-later, all FE heads got eight extra exhaust manifold bosses cast into them. Some heads got drilled for the Fairlane/Mustang pattern, others for Galaxie and pickup applications. These '66-later heads han be drilled either way or both ways. '65-earlier heads lack the eight extra manifold bosses on the exhaust flange of each head, and cannot be drilled because there is no extra material there - four bosses are clearly missing and the four in the water jacket are also missing, meaning you'll probably hit water if you drill.
The engine you have will work great in the Mustang, but you'll have to learn the details of how to retrofit your block to Mustang motor mounts, and you also need to know the heads will be TOUGH to bolt up to headers, because you can't cheat and leave the bottom bolts out, as you can if you have 14 or 16 bolt holes per head.
Note also that the exhaust port position is different between the '65-earlier (also includes all 427s, C6AE-R, and CJ heads), and the 66-later small-runner heads, as the later head has lowered the exhaust port 5/16", meaning the two port styles require two different types of headers, if you expect to properly port match and seal the headers.
