Baggies a must and there can't be enough pictures taken. REPEAT the more pictures the better. Also pictures as it's going back together. I was looking at PP one night and something that was being discussed made me think, more like panic "did I put that back together right". Looked at the pictures and sure enough it was on right...
Doing a rebuild of a 911 engine should be on the list of "need to do" in one's life. Enjoy!
