I've been threw about 30 pages on how to & what i need to do an AU engine into an XG conversion but i couldn't find a list of things so can someone or more give me some advice on how to go about it. Thanks all for your time.

Ive done this conversion. The front of the sump will not clear the sway bar without modification, of using some form of spacer on sway bar mounts. Use XG mounts. you can use log manifold, using BBM get slightly more involved.
