Check youtube, if you did a straight six before, they are all about the same, except for the DOHC!! Have the head magged if cast or pressure tested if alum! I cant remember, been awhile. Dont forget the straight edge!!!! You understand what i have posted? IF not you may need to get some hands-on help.
