Umm, I feel dumb asking this... buuuuuuut ->
4valve 4.6 longblock versus 2valve 4.6 longblock: is the height of the intake manifold deck the same (ya know where the intake seats on the heads)? For example, pick a point on the block like the top of the block between the heads, and measuring vertically to the deck of each head where the intake manifold sits, is the distance the same?
