PO rebuilt the head or a shop did?
Some shops run really thin valve seat widths that will "pound in" (quote from an actual machine shop). This makes the valves seal up well initially, but can cause valve seat and valve face wear issues, which can require lash adjustments until everything finds a happy medium. Not my preferred method, but it's commonly done.
