65 Valiant 170 changing oil pan gasket is it easy?

I'm debating changing the oil pan gasket on my 65 Valiant 170 because it's really nasty. I've already changed, intake/exhaust manifold gaskets, valve cover gasket, timing cover gasket, oil pump gasket. I've got the factory manual and it says you have to remove the center link and raise the engine 1-2 inches. Where the car is it may not be possible to lift the engine because it's outside where there is no garage access and no smooth driveway. Can you raise it still with a jack and get it off? Or do you actually have to raise the engine or can you wiggle it in and out?
