Just how hard is a EM R&R on a CGT??

Greetings Audinauts,
I was just thinking this over today (the cold mornings seem
to make the exhaust manifold leak louder)...
Anyone have a real-world, step-by-step description of the
exhaust manifold removal procedure, specifically for a Coupe
GT? I understand perfectly what's involved (get the intake
out of the way, remove cracked EM, remove broken studs by
hook or crook, installation is reverse of removal etc
etc)... but how long does this really take, assuming access
to reasonable facilities and tools? Thinking of putting a
4kq "header" in and solving the last outstanding mechanical
question mark on the '85. Wondering what the collective
wisdom is on this noisy subject. TIA,
Rob
