I found I had to oblong the bolt holes on the bracket that supports the manifold. I oblonged the side that bolts to the header. The one that bolts to the block & manifold. I also removed the fuel evact canister on the firewall. I reused the oem gasket also. Better than the ford replacement one. I tighten them in sequance to 35lbs in 3 steps. Top to bottom then top, ect.
