Finally! My heads arrived and now reside on my motor My next ? on this subject is when should I re-torque the head bolts? Everything seems to be working pretty good- no leaks, whistles, hisses or strange happenings so far after two days with maybe 20 miles drive distance and about 30 min. run time sitting in drive adjusting idle and timing. After getting vac. gauge the best reading I could get was 17 in. at 850 rpm idling in park. This all right with a mild cam ( 204-214 dur. and .420-.442 lift)? Am running 1.6 rockers so that is bumped up some. Anyway, have Mr. Gasket ultra-seal gaskets but I should probably re-torque anyway? I know this is basics for a lot of you but not real routine to me. Thanks for any feedback from the more enlightened
