Help removing exhaust manifold
Replacing the head gasket on my 2003 3.0i, but I can’t get enough room to slip the exhaust manifolds over the studs. Anyone have any tricks for getting these out? I bent the head shield out of the way with a mallet, but it doesn’t seem to want to go any further.

When I replaced the OEM manifolds with tubular headers, a number of the studs wound out with the frozen nuts.
You might try (not a recommendation) double nutting the studs and try winding them out of the head. This is what I ended up doing. Luckily I did not damage any threads in the head. OR just remove the head with manifolds attached.

Not exactly what you're dealing with as the manifolds go, but shows the extent of the manifold overhang to the collector flanges.

Not sure I fully understand the situation, however here is an image from when I replaced the exhaust manifolds and gaskets - removed the air pump valve and hose for clearance if I recall

Might be that the M54 head sits a bit closer to the strut towers and other interferences than the S54 head

Just a sort of update in case anyone has the same/similar issue, you are in fact able to pull the head and just leave the manifolds intact. I did end up snapping both of the side tensioner guides, but I think as long as you know what you are doing ( I didn’t know they were there D: ) then you should be fine
