A little update.
I got it in and running, but the HG was leaking everything everywhere.
Turned out the head bolts were not at correct torque.
My torque wrench had snapped inside as I was installing the flywheel - I got another and thought nothing of it and finished the install.
With the head bolts loose, I can't trust that the main and rod caps are at the right torque.
So the engine is out again for retightening.
Anyway, the exhaust is installed and fits nice and tight.
