Gusser, I see that you have tried mounting the billet intakes and not had to much luck by the sound of it. I just forked over the 200 bucks for a set also. I have not yet tried to install them but to the naked eye it sure looks like the increased angle on the billets compared to the original cast manifolds could definitely cause me problems. From the sound of your post I would be better off not wasting my time trying to fit them. Maybe the adds for the billet intakes should not state that they are just a bolt on application for the BA and Speedmaster. Your comments would be greatly appreciated.
