Default Install Imco manifolds

Doing install by my lonesome can be challenging, but finding this to be most difficult.........even thou BB aluminum manifold much lighter than cast iron
very difficult to drop these in and align with engine block bolt holes...............anyway, does anybody know if the manifold bolts have to be torque tightened?

Torque wrenching a part in a ridiculous confined space goes out the window when you can barely can get a socket on it..........."Oh the joys of an engine on a stand!!"

Skippy, Don't forget to re-torque (tighten) after a couple of heat cycles.
