When the manifold studs broke on my 03 5.4 I replaced the manifolds with a set of stainless steel shorty headers . One of the studs had broken off below the surface and I had to build up a bead and weld a nut on it . Its not that bad of a job on the 03 once you take the inner fenders off and then its easy access to the manifolds. The inner fenders are held on with a few bolts and snap fasteners. Done in one day then re torqued the bolts 2 wks later. Made a nice improvement in power and mileage.
Having even a cheap mig welder makes short easy work of this job. Welded nuts onto my studs and with all that heat they backed out like they where installed 5 minutes ago :C
