Ok well i have been on the local AZ Supras forum and im having a hard time finding a machine shop. Theres a lot of controversy over which one to go to. A lot of people have good experiences with one but then someone else had a bad experience with them. Im looking for a machine shop anywhere in the mid region of Arizona (anywhere from west valley to east Mesa within about 2 hours of driving, Tucson is a possibility if nothing else) that CAN get their machining down to 30RA for a metal head gasket. Thanks for any help.
