I need some advice on replacing/rebuilding the head on '47 Farmall C. Where would I go to boy a used or rebuilt head? AND should I replace the cylinder sleeves while I'm at it?
I think they do but just not much here as far as Farmall is concerned. What engine does that tractor have? This is the forum I use for Farmall support. FarmallCub.Com
There's not a ton of activity on there but if you post a question you will get a response and there are some really good Farmall guys on there.
I'd try cleaning up what you have before going out and buying new. From the photos, that just looks more dirty than anything else. There is at least one stuck valve, but that may be able to be repaired.
