Default 4v heads on a GT?

Can the 4v cobra heads be modified to fit on a GT? If so has anyone done this what does it entail? thanks

Can it? Yes. Is it even remotely worth the time, money, and effort when you can buy a used motor out of a wrecked cobra and drop it in for around the same price? No.

And also dont forget that the cobra heads make HP MUCH later and higher then the GT.. there is a reason they came with a forged crank.. if you think your GT will rev to 7k as is... go for it [8D]

To do the swap you would basicaly need every single supporitng mod off the top end. Heads, Cams, Timing chain, Covers, intake, throttle body, etc.
