Default Cobra 4v head swap

I assume this is possible. I tried searching this form but search is not working, I am new to 4.6 mods but not new to Mustangs. My son wants to up the HP on his 80k 96 GT auto. Can 4v heads bolt to this short block? Is it worth the work ? This is dd and not race car. I am tring to talk him in to pi swap instead. His last 90 gt had way more power than this one.

The 4v swap is involved and complicated. You dammed near are going to need a donor car/motor to get the job done.

If you really must go 4v then just get a complete 4v motor and save yourself some headaches.

The PI swap is much easyer and should be much cheaper as well.

Yep. Its definitely possible but not cheap or easy. PI swap or new car would be the way to go.
