Update and Advice

[D24TCJ5]

Hey guys, I've been quiet for a while but I need some help. I have a couple problems and I need a few questions answered. I have a huge project coming up this weekend.... I plan on changing my exhaust manifold gaskets, front main seal, and my valve cover gasket. What does the exhaust manifold hardware(nuts, bolts, etc.) need to be torqued to? 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,
Nick
