Ok, after ALOT of swearing and 3 days of work, I finally got the head off of my 1998 Mazda B4000.
The history of the truck as I know it is, at 50,000 kms, the heads were replaced by the previous owner.. For what reason exactly I am not sure. Now at at 150,000, and when I bought it, it has a burnt exhaust valve on the number 5 cylinder.
What I am trying to figure out is, if theses heads are early model castings or later model ones. How do I tell?
Numbers on the head that I have found are C8S1A....FO91 on the front of the head, 99884 on the other side. and the other is 95TM 6090AD
