This was not an easy task to do. I actually had to sneak the sawzall down next to the header and put a small slice into the frame so the header would come out, w/o unbolting the body mounts:
Its very minor, but i intend to clearance this area a bit more and make it look nicer, once the engine is out.
Moving forward, i succeeded in getting the header off the head:
I am a little concerned for the condition of the header flange however. This still has old gasket on it that needs to be removed, but it still looks a bit rough in my opinion:
Considering headers for a 460 are pretty expensive, i think its worth my time to clean them up, sand blast em, and see if theyre gonna be ok to reuse. If so, im going to remove the tube for AIR, since the broncos dont use that emissions system anyway.
