I live in Washington state and it would be great if I was able to do it local
any other advice in making the motor dependable would be appreciated.
Thanks

You should be able to find someone in your area that can re-work the heads. Just search for a cylinder head shop in your area. No use to ship those heavy things around the U.S. if you don't need too.
