this kind of thread should be in the "state chapters" area so i'm going to move it there then you can share the link with others from washington.
I just finished rebuilding mine. Got most of my things from http://www.engnbldr.com/ . hes right down the street from me in portland but deals everywhere.
yes very good source of parts and gaskets
And i've never looked for it but there must be a writeup on a 22re headgasket between the low riders, off roaders, and clelicas
You can do it 
but if you really don't want to someone local up there might be able to chime in.
ive said this several times in the past couple weeks not sure if you posted it or not but
there is absolutely NO DIFFERENCE between the celica 22R/RE's and the truck 4wd or 2wd engines. the only difference was from 82-84 celica engines were EFI where the trucks didnt get EFI til 85, but even though the 82-84 celicas had efi they had the same block / head and pistons as the 82-84 trucks
