It'll work out well
The best way to do this in my opinion is;
1. Use the 3.2 long block and just use it as though it is a 3.0. Do not change the cylinder head gaskets unless required.
2. Use all 3.0 timing gear, front end parts, timing belts, pulleys, oil pan, oil pump,(some say the 3.2 pump is better, but I don't believe it), flywheel, clutch assembly, wiring and motor mounts.
3. Notch the cylinder head to match the 3.0 alternator (search for these instructions, you'll need them). Remount the 3.0 coil assembly using the untapped bosses in the 3.2 cylinder head. (drill and tap two bosses so that it sits in the same relative position as the 3.0. You'll see.) Drill one hole to provide a third lift mount for the front engine lift. The forth hole can't be drilled.
4. Except for the bolt holes (The newly tapped holes make the installation look OEM. Do them) everything is just as though you were using a 3.0 long block.
5. Use the 3.0 intake and all related intake parts that attach to the cylinder head.
6. All exhaust stuff switches over.
The result is a more powerful motor with significantly more torque. I think the reason that Ford didn't do this is because the drive train wouldn't take it. Mine spins the tires in second gear at will. It did not do that with the 3.0.
