Thanks, Bill, for the info.
On the front of the passenger side Head, I can make out what looks like an "M". There are other marks to either side, but too much grease and grime to scrape off easily. It's snowing, so I'll wait for a little "drier" day to clean more.
It's good to know about the seals possibly sealing themselves. Should I use some of that "stop leak" stuff, or is that not good?
Thanks for all your help, I know I have a lot of questions. This is my first project truck, so I'm new at it.
