In my area machine shops are not that popular due to the fact that tracks have been closing up and you can order a create engine for less than rebuilding and have a warranty too. I believe that it's a Napa store not far from me but they don't do 3 angle valve jobs anymore because of the time involved and not much call for it anymore. A lot of the part stores don't turn brake drums or rotors as we are going more towards throwing things away, it's sad but true
