Hughes "retro fit" lifter not pumping up!

well this set of hyd lifters are pumping down , but at the least the springs in them are keeping the pushrod tight in place , still can plunge some of them and not others at all . seems their going to be rattley on overnight as well . but i'm not getting paid on this issue , this is on the cuff . even my cam grinder that set up me with these said , '' no more '' . so i'll keep me fingers cross , and hope they '' bed in ''. oh and this guy wants no noise vavle train , rhoads ad says '' solids like sound at low rpm ''. not what he wants , may end up installing a hyd roller set up . factory chrysler type hyd rollers fit in the block between the head n lifter bores . but the push rod doesn't clear the hole in the head for the push rod , so i'd be peeling in more then just lifters . this sucks .
