And is there any specific order I should take them off? Also my engine is in a Jeep and I have plenty of work space will I still need to lift the engine to replace the front main? What about timing? I have so many questions and I would greatly appreciate even the smallest bit of help.
Thank you so much,

Why are you changing the exhaust manifold gaskets? Pull them off in this order with a cold engine: 1,6,2,5,3,4. Make sure the gaskets are lined up when installed, the studs are offset from the ports and the gaskets will fit either way but when installed wrong it will block about 1/4" of the ports, it's an easy mistake, I have seen two engines I have worked on with gaskets installed wrong. I'm not sure on the torque spec though, I will look it up in the book. Tighten manifold bolts in this order 3,4,2,5,1,6.
Is the front main seal leaking? That's not a fun job, even with the special tools. I would recommend cleaning the engine up real good and pinpoint the leak if you haven't already, it could be the valve over gasket leaking on the front and draining down the block behind the cover making it look to be the front seal.
It could also be the oil pump mounting gasket. If I were going to do any of those two gaskets it would be a good time to replace the timing belt, idler pulley, and water pump.
Find a good quality one piece rubber valve cover gasket, they seal much better then the four piece cork gaskets and are reusable.
