Will a 5.4 head work in place of one of my 4.6 heads? Guy I bought them from sent me one of each. Said they are the same thing.:confused:

They are totally different. From my understanding the 5.4 head is larger than the 4.6 head. You might have problems bolting them up to your 4.6 motor.

No, they are totally the same. The 5.4 is a stroked 4.6 and the block and intake is the difference.


Good info on the 4.6

The 4.6 and the 5.4 are EXACTLY the same.
