So I have to pull the heads off my 2001 Mustang Gt ... and well I was looking for parts online for my car and ran across DOHC heads.... If I bought those for my car what else would I have to do to the engine Or whatever else to make it work... or can it even be done.... how different is the GT block from the Cobra block ?

If the GT and Cobra are both 4.6 they are enterchangable. With the heads you may have to change the programming on the computer.

just cause they are both 4.6 dosen't mean they are interchangable the gt is a SOHC and the Cobra is a DOHC thats why I asked the question to me with an answer Like that it seems like you don't know what your talking about and I have no clue why your answer was chosen as the best

If you change the cylinde heads, you need a new intake, new valve covers, timing chains, and the emission parts are put at different places.

Um, I Race Cars...
You mean the 05-07 3 valve motors right? Oh and my 06 is an aluminum block car, not iron.

The one poster earlier was talking about a Mclaren motor.... actually the block is italian... Teksid. But the motor is pure ford v8.

There were two different Cobra engines. One was made by Ford, the other was made my McLaren. (If I remember right). The McLaren was totally different engine, although it was an overhead cam motor. It was not a Ford product at all. So what you need to do is contact your friendly Ford parts department. They can best answer your questions. AND save you a lot of money in the process.

Dude you cant do it! If you have a 4.6 SOHC mill you cant just bolt on DOHC heads...Single Overhead Cam is a totally different animal than its Double Overhead Cam brethren. DOHC is fairly exotic and primarily used in high rev, high performance applications. A DOHC V8 motor has a total of 4 camshafts, one for intake valves and one for exhaust valves on each bank. Your SOHC mill has a total of 2 camshafts, one on each bank operating both the intake and the exhaust valves.
