The Mustang bldy was changed in 1972 and one of the specific changes was that the 429 would be a bolt-in deal. Don't know what engine mounts, exhaust manifolds, etc you might need but the aftermarket header manufacturers, etc should be able to help you out.

For a 1972 Mustang a Holley 750 or 850 cfm would be the way to go. Which one you use depends on the overall build and engine use.
