John,
IMHO, the head gasket is blown. Retorquing won't help you a bit.
As far as the exhaust manafold/pipe connection goes, I left it connected on
my TR3B. All I did was pull the carbs, undo the bolts holding the manifolds
to the block, and let the exhaust pipe hold both manifolds. Plenty of room
to pull the head.
Good luck
