I have puchased a GM Marine 502 HO longblock
I want to back to or as close as possible to the original 500 EFI specs
Can someone reccomend who I should have work on my Heads?
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.
