Hughes "retro fit" lifter not pumping up!

there is an tolerance issues , within the 80 or so flat tapper hyd i've dealt with . poor machining practices and grinding . fth are about a hundrede a set , but rollers are 500 n up . seems that someone should be checking the rollers for good or bad . had a tech from hyghlift johnsons (topline) tell me that every lifter is checked before it leaves the door . oh ya lying bastard ! i got a set from them that had three lifters that where rock hard , the pistons would not move at all and one of the 16 of them would have been okay , those where hand picked my *** .
