    LS7 lifter and milled head questions!!!

    I know use search button and adjustable length checker but I can't have my DD down for waiting on pushrods . My heads are 706's cut to a 57cc chamber which is 0.030 I believe. But I've also been reading that LS7 lifters cup is 0.050 higher and should also use a shorter pushrod. So should I get a pushrod around 7.32 to be safe??? But like I said I know the right way but cant not have a car for a few days

    02 Fully forged Iron Ls1 233/239 595/603 112lsa,
    milled, ported& polished heads,
    K&N CAI, shorty headers,
    off road x-pipe, Pypes M-80s dumped,
    TCI 3600 stall ,TransGo shift kit,
    True Trac w/3:73s, 4/6 drop,
    and a Fast LSXRT 102
