OK Al, I'll tell you my reason for upgrading.  My engin= e has always had an occasional intermittent misfire, usually on climbout bu= t occasionally in cruise.  It happens infrequently just to one compres= sion cycle and then it clears up.  Obviously, this does not insti= ll confidence with pax, or myself either.  I've tried various solution= s, but the problem persists.  I'm hoping the hotter spark from the 585= coils will cure this annoying problem.  I'll report back after instal= ling the new coils and test flying.
