Well I'm at it again. I searched and searched and maybe I'm terrible at searching but I didn't come up with anything.


Long story short. I have an '02 that blew a head gasket. Yanked the cylinder head to find it cracked. I have sitting on the floor an engine from a '98. Yanked it's head off, it's in great shape.


BUT! As far as I can tell, the only differences are-


(1)- Casting numbers


(2)- Rocker arms. The newer engine has bolt down rocker arms, the old one has a stud with a nut. Is there any reason they wouldn't be interchangeable? The pushrods and what-not are the same length.


According to O'reilly's website, the valves are the same, the head gaskets are the same.


SO! Can I just swap 'em over or what?


Thanks guys.

 

Use the 1998 rockers on the 1998 heads. Pushrods and Lifters are the same part number between the two years.

 

Well that's exactly what I did and it worked great!


Now I just need to see how badly this frame is bent...

 

glad it worked out for you. Thanks for letting us know.
