putting in a newer 22r
 

So i bought this yota earlier this week, pulled the engine yesterday and am getting a newer 22r (same engine) at the end of the week. the old 22r is going to the shop.
my question is while i have my engine out, should i clean or take care of anything while waiting for the newer 22r to return? this is all a huge learning process for me since i have very little automotive experience previous.
and just cause i attached some pics of the engine pull :) any help would be sick....
