I am doing top end on my 9 N . It has original valves and the # 4 exhaust valve was sticking . I have ground the sets , checked the gap on the valves . they are all in specs. I have a new gasket kit . Inside that kit there are 8 -quarter sized , rubber washers and I don't see any evidence of them in the tractor . What are they and where do they go ? I was told that on some of those models , they were not used .
 
Do they have a hole in the center about the size of the valve stems? You need to remember that your tractor engine is 1/2 of the old flat head 239 cubic inch V-8 engine. Sounds to me like they are valve stem seals and would have been used on the intake valves. The reason there are 8 is because most of those valve seals kits are also used on the V-8 engines. It was simple just to have one kit of 8 rather than both a kit for a tractor and
