clearance between RH engine mount and exhaust manifold
This is just a warning/cautionary tale for those working on exhaust manifolds on these earlier model modular engines.
I'm so glad I decided to mount the exhaust manifolds on my '99 4.6L before dropping the engine in. I'd be pretty upset if I hadn't.
It turns out, there is one stud on the RH exhaust manifold that doesn't have enough clearance from the RH engine mount to get a socket over it. I tried to re-position the engine mount as far away as I could and tried other sockets I had. Nothing worked. In the end, I ended up taking the engine mount off and hitting it with the bench grinder to make room for the socket.

not enough room to get a socket on the nut

Why is that area of your truck so clean? Your post has stimulated my memory and I vaguely remember having similar problems with my 4.6. The 5.4 has plenty of clearance but when I swapped engines I bought new mounts. Not sure but I think the new mounts do not have the area that drops down like yours.
