32v 4.6 heads on 32v 5.4

[FineLineMtrSprt]

Just like the title says...do the 4.6 heads just bolt on to the 5.4 block..or whats needed to do the swap if anyone knows.

So yes, they will bolt on. What are you doing? What year nav block? I have a file with the complete topic some place. If I remember, those heads are just about the same?

I think he will have problems getting an intake for that set up unless he uses a spacer with a cobra intake. the 5.4 4 valve heads definitely have a different intake port, its way larger

This... The intake ports are set differently on 4.6 heads vs 5.4 heads. I think he would need a custom intake or an Australian BOSS intake...
