What would 7.562 ball and ball pushrods be from?

1/32 is .03x preload, guys are talking .06x preload or 1/16 inch so a little longer would only get you a little more preload but that is taking a stock base circle cam into consideration. Why F with 19 different custom pushrod sizes when you can get 273 adjustables for $150 here all day and dial it in with a wrench? Are you running a magnum head? We can add that measurement into the database now, hydro rockers with a magnum head.
