If it only takes 30 minutes more, I would probably remove them like Rick does if I had someone to show me how, but I don't want to make a mistake on a customer's fish and currently I know my method works fine. I do have a DVD of Rick's where he shows how to do it, but seeing it and trying it are two different things. I could see it making it easier to clean out the head and detail. One of the things I have to rebuild a lot is the throat latch because I often tear it when cleaning. I'm not sure if taking the head off would help prevent that.
