If you're swapping both, I'd pull them in & out together. Also while things are out of the car, replace ALL external transmission seals, and I'd replace the engine oil pan gasket too. These jobs are nightmares with the powertrain installed but pretty simple when the parts are on the floor in front of you. You'll need a cherry picker than goes way high, or a block & tackle setup, as the engine & tranny has to go rather high up to clear everything on the way out (don't forget the car will rise up as weight is removed).
Whatcha doin' with the old engine, btw?
