all i can remember off the top of my head is that the ports are 74mm centre to centre, if that helps

the f4i exhaust manifold uses individual exhaust retainers- i.e., there is no flange across the whole manifold. all you should need is the center-to-center of the pair of bolts that hold each runner on, as well as the o.d. of the tubing you are using for your runners.
