My spec book lists between 1.775 and 1.7915 with various stops in between. It is primarily for various compression ratios and depends on year as well as combustion chamber size. As long as you build the engine around the piston used it is probably not a big deal. It was also well known that the FE engines tended to vary from side to side, one( can't recall which) had more clearance than the other and was usually corrected when blueprinting......at least according to Dyno Don....I will yield to his superior and wider experience.
