its interesting to see the extra higher raised boss on #2 & #4 in Vin's photo (Msiert's photo)....the parts catalogue actually gives 4 separate part numbers for the two 'twin branches' of the manifold....I guess a heatshield manifold and a non- heatshield manifold.
And yet, Nick, your bosses look normal height, like mine (a non heatshield S4, although #4 boss on mine actually has a hole, just not tapped!!), but yours has always had a heatshield I believe?
