04 STX 4.6 2v with 5.4 3v heads .... Is this possible ???

Just wondering if the heads off a 5.4 3v motor can put installed on a 4.6 2v an use a 5.4 3v intake or maybe add a supercharger??? Any advice would be thanked


Don't really know much about these engines only reason I ask

Not sure if the 3v head will fit but a 5.4 intake won't fit the 4.6. The 5.4 has a taller deck height.

Unless you already have the 5.4 heads, why not use the 3v heads used on the 4.6 mustangs?
