04 Spec V motor swap

I blew the motor in my 04 spec v, and being on a tight budget, I bought a used qr25 from a junk yard with 67k on it. Aside from the obvious, (loctite butterfly valves, remove pre-cat, replace fluids, gasket set, etc) is there anything I should know or be doing that isnt obvious? Anyone who has done a straight up qr/qr swap with some pointers would be great. Thanks. (I have a decent write up swapping a qr from an 05 altima to an 03 spec-v, and obviously a FSM. I just would like to cover all my bases, and we all know experience tells a lot more than words on paper)

Probably be a good idea to look into the precat of the newly purchased engine and see if there are signs of burnt oil before you go through all of the work. There are so many problems with oil burning QR25DE's that it makes me leary on any used QR engine.

Yeah I'm aware of the oil burning issues and of course the precat issues. I plan on running a compression test before I put the motor in, and running my catless header I have on the car now. I couldn't afford a rebuilt/reman motor, this was really my only choice. As long as I can make it last another year until I can pay down the loan enough to trade it in I will be happy.
