Hi Tony. Thanks for providing this information. I am hoping to someday put together an accurate tech article on the 9-series heads because these questions come up frequently and there is a lot of really bad information floating around. I was born in 1967 and my father used the 9-series tractors since 1952. We ran into some really difficult financial times in the 70's & 80's so we actually ended bringing dad's WD-9 & Super WD-9 out of retirement in 1982 to try and continue farming. In spite of the "tough times" it was a great experience that I wouldn't trade for anything. I had a chance to actually work with these tractors for about 5 years and the "collector bug" bit me. My collecting addiction grew from those experiences.
Where I am going with this is that there is a gap in my knowledge of the 9 series tractors because I was born long after the last 650 was built. I had the good fortune of knowing some mechanics who worked on them when the tractors were new--so that has helped.
You have some great details that I have never been able to find and I welcome that sort of information. Where did you get those details? (Like the bushing, linkage changes, studs, S/N breaks, etc.). I think I have installed the newer style head 278292R1 in place of a 260692R? before and I don't recall having to replace any of the other components. It was a while ago so maybe I have forgotten something or the tractor I was working on may have had parts replaced previously that I didn't realize. I am going to study my WD-9 that is in my shop today! Anyway, I am trying to sort these things out and I really appreciate your help.

Today's Featured Article - Product Review: Lead Substitutes - by Mike Schordine. Lead was oriinally added to gasoline as an upper cylinder lubricant. It lubes the valves and seats. If you rebuild the motor, you could use hardened seats and valves, and unleaded fuel. But if your old tractor runs good, a simple lead substitute added to the gas is a perfectly reasonable solution. And, if you are like me, your tractor is under cover, but it sits outside. So with every temperature change, the humidity in the air collects in the fuel tank, in the form of water.
