In the process of rebuilding SC 8029123 (was really stuck), I am ready to grind the valves but my manuals only list the valve dimensions for the older/smaller engine, and I need to order some new seat grinding stones. So I have three questions: what size are the valves, what are the correct manuals for 1953-1954 SC's, and does anyone know seat stone sizes or a vendor/part number? As soon as I can I'll post a few pictures of the rebuild.
Thanks, Glenn
