New to the nation, need a little help finding a good shop. We have a fleet of F-350 Powerstrokes and one by one, we will be needing to do head gaskets. Can some members recommend a good shop to have this done in the Portland/Vancouver area that is both fair and reasonable in price, but more importantly, trusted by people who drive thier trucks. We have one that needs to be done now, and pretty quickly because we are moving some of our fleet around within the company. Thanks!
