Are you talking about taking the heads off the 5.4L engine from the modern GT40 and trying to fit them to an old 5.0L? I can't see how this would work unless I'm really missing something here...


Well some one said that cast iron GT40 cylinder heads could fit on a 5liter v8!! now I don't know if that's true or if they had to port or some thing.


Okay gotcha. I was thinking the NEW GT from the 2000s with the 5.4L. Googling GT40 heads 5.0 turns up a bunch of results...


I am sure the 5.0 GT-40 heads will bolt on to your block, BUT, it definitely will not make you a GT-40 Bird. You don't say what you are after with this setup... if you only want bragging rights to say it has GT-40 heads, then job is done. BUT, if you want a Hi-Performance setup, this is only a start and I am not sure even how good of a start. Port, polish, balance,, etc. maybe a Magna-Flo exhaust system, and more and you will have some bragging rights. Either way, good luck.
