Chevrolet Camaro 1967-2002 - installing motor today

Im finally putting my motor in today and just wanted to know if it easier to get the headers on while the motors out. i droped the cradle down last night and I'm doing it from the bottom but i don't want to f the headers up. and also should i hook the wire harness up while its out or wait till its in. any other do's and don'ts would be awesome too. thanks

Def headers on...

Def easier to put them on before installing if you're working by yourself but it's still not that bad installing them before tighting everything down.

yeah i learned that it would have been easier to do so before or at least the driver side cuz i had to remove the motor mount and jack up and remove the alternator to get the bolt in, also i now know the trans dip stick should have been installed with them out.
