Thanks for the feedback. If I end up doing any rebuilding I doubt that I will do anything other than follow the Shop manual. I wanted to understand more about the options and you answered my questions. You know, its hard for me to get past the fact that these old engines just "keep going" and that although the methods for repair have been changed greatly by advances in machining and technology, the old methods produced some pretty solid results. I'll be following your progress and thanks again.
