Could be a 4.6 version of the DOHC 5.4 GT engine!!! Sweet!01GTB said:They are saying only intakes and exhaust that happen to be found on 5.4 engines will fit. And only specific ones that use these heads, at that.
First thought, it's a clever joke.
Second thought, I am not sure they would want to provide information that might cause people to buy a set of cylinder heads, now, that was wrong.
Now see, this is stuff I like to hear
Edit: Although after reading it 10 times and thinking it they would fit 5.4 only, the Bullitt intake could possibly be the only 4.6 intake that might fit these heads. Regular 4.6 Cobra stuff will not fit even if installed on a 4.6 block because of the port shapes.
