Whats the rundown on swapping a l94

[Jmh68C10]

Bought a L94 (6.2) out of a wrecked 2011 escalade.I plan to run a new 4l75e trans. So far I have researched that I need to swap oil pans to a f-body pan (in the process of swapping), headers(open to recommendations, considering sanderston ), and a custom wiring harness ecm (considering pci or spear tech ). My question is what else do I need to make this a good swap. I realize it is not the ideal choice of motors but I have it so at this point it makes the most sense to make it work. Looks like I may need to remove the fuel management system. Any knowledge on this will be highly appreciated.
