Does anyone know of a web site where they have step-by-stupid directions for swapping heads. I've read some threads and they seem pretty scary with the timing chain tensioner. I really don't want to get halfway and then realize that I'm really a dumbass for not doing something else first. I'm at work right now getting ready to tear into this when I get home today, but I'm really here trying to get all info possible before. Are my priorities screwed up, Nope....Thanx to all that have been patient with ans. my ?'s, i gotta lot of 'em, and the advice too....
