    The locating pins for the manifold are in a different location vertically on the later 4.0 FI head (my 94 4.0 FI head is this way), the 4.0 carb and early FI head may be the same pin location as the 258 head unsure of that though. The 258 manifold if it is aluminum can be modified to fit the FI head pin location so that the ports line up. Hope this helps you out.
