The secondary linkage is different and must be modified to fit. The fuel rail on the ones I had apart exit the opposite side of the engine and would need to be swapped out anyway. No need for the 3 liter heads to use this lower intake as it's the one I'm using on my 3 liter with the 2.5 heads. The ports are cast the same size on the two heads, no difference. Of course mine are "missing" the secondaries so no linkage modification was needed other than to remove it.
