I had the heads on the engine, and got it close to position, then slid the motor mounts in and lined up the trans and motor mounts all at once. Then started tightening stuff.
I would definitely leave the exhaust manifolds off to give you as much room as possible along the sides.
Don't forget to reattach the trans vent tube to the back of the driver's side head. Easier to do with the intake manifold off.
