I have not done one of these, but have too much experience with the FJ1200 motors which are simular. I allways took safety wire and ran it thru the cam chain close to where it came thru the head. Went thru front and rear sides of chain. This allowed me to tie it off around a cam tower and made for easy retieval when I dropped it. On the cam caps, a litle brake clean on the ends of them and mark them with dot for each tower and to the front. From the article posted to help, it sounds like these heads are made like the 2.2 dodge heads. The install caps and then line bore them I guess, so its not a good idea to swap around.
