what you have experienced is a problem with 2 groups. first, hughe's  selling 
something that he new there was a problems with (he ain't the only  one!), 
and second there is a hydraulic lifter problem out there. hughe's stating  that 
there is only one lifter company is somewhat correct. several years ago the  
cam grinders bought their tappets from Eaton. Eaton quit making flat tappets 
and  this decimated the performance folks who were used to having a high quality 
 hydraulic tappet. the cam manufacturers were forced to buy from a company 
that  produced second rate tappets. i didn't pull this information out of the 
air. it  came directly from Mark Engle of Engle cams. in my last build i went 
thru 2  hydraulic camshafts. the first was a comp. cams xe275hl. i lost the #3 
intake  tappet on break in. the tappet was spinning but just erroded away! the 
second  cam was an engle k58. cam broke in fine but the internal valving in 
the tappets  wouldn't get them pumped up due to sloppy tolerances. i finally 
settled on an  engle k65 solid after a very lengthy discussion with Mark Engle. 
i'm very  satisfied with this solid, wish i'd done it in the first place,  and 
don't recommend any performance hydraulics due to tappet failures. i'm of  the 
understanding that hughe's is using chinese tappets now, and don't know if  
there are any quality issues. racer brown is offering an "optional"  hydraulic 
tappet now. until the tappet problem is solved i will avoid ALL  hydraulic 
cams, especially performance cams, like the  plague.
