Broken manifold studs on my 4.7 PITA!!!!!

Fishy, I don't think the headers added much. I would not put them on if the manifolds are still sealed up. If they start to leak, then you might want to put them on. I actually need to get it in the shop this week to do the first after driving tightening, which is not going to be much fun with everything back in, and I will probably use an end wrench to tighten them.

There is not much room to get an impact in there, i used some sockets, some open end wrenches, cut some heads off with a die grinder, some with a cut off wheel on a grinder, welded some nuts on to get the rounded heads off. There was alot of different tools used. The drivers side was easier due to more room, the passenger side is close to the frame rail.

Good luck
