Ok, here's the deal...in a fit of absolute brilliance, I busted the head off one of my fuel rail bolts. Now, I can either pull it all aprt and drill it out, however, I have access to very inexpensive MARK 8 manifolds with fuel rails included. Here's my question: Is the mark 8 lower intake piece compatible with the Cobra Upper piece and is there any real difference in performance between the two units? It's a F/I application so im not concerned with loss of velocity. Can I run these two pieces together?
