This is my second post about this tractor. Here is the link to the original so you can get more details:

I pulled 7 of the 8 valves out. One is stuck so tight I don't know if I will ever get it out. I am considering just replacing all the valves. They are pitted pretty badly, especially on the top. I can't even get a lapping tool to stick to them, and I would be surprised if I didn't damage them getting them out. Also, while cleaning the top of the block, I noticed that the piston has a lot of movement. (see video below) I don't know if that's normal or if that means it needs new rings. I also included some pictures of one valve after I cleaned it
