        Just had my head examined; then holes re-drilled and shaved.

        What are the proper specs for torquing it back on?

        Oh, yes, and now that we have found that it's supposedly 118 lb/ we need to know the valve adjustment info . HELP! ANYONE!

              Hans,

              Since all of most of my tools including my brain think in English units I created a list of some of the engine specs in excel.  I did spring for a few of the manuals and I am happy to have them but i do not mind sharing the info. Please use with care as these have not been vetted by anyone.
