3.5 heads are 36cc, 4.6 heads are 29cc, so your cr will be shot to bits.
Sump is different, you'd need to check.
Fuelling will be totally different so it very much depends on your intakes.
Ignition on the 4.6 is 4 coil lost spark, 3.5 it's single coil and distributor.
The swap can be done but you'll need to spend some money, main issue is the front end/ignition, they are interdependent.

Mmmm, i was under the impression the front cover of a 3.5 fitted a 4.6 block but agree a spacer will be required to bolt the damper down. the c/r on the heads will be ok if you use tin gaskets rather than composite. fuelling will be anyway you want depending on which carb/efi route you take. ignition will be single coil and dizzy if you use the 3.5 front cover OR 4 coil/lost spark with an aftermarket ecu on efi (megasquirt etc.) so i still think it can be done
