Mustang 67 - 289

I think the rear end swap is a sound idea. If you do look at after market alum heads, like TFS or Edelbrock you must also use hardened push rods, stud type roller rockers, and you cannot use a cam that has more than 230 degrees duration when measured at .050. You can get your pistons fly-cut or use pistons made for the TFS heads. Also push rod lenght must be measured to ensure proper valve train geometry.
