problems with rocker arms

I converted from ductile iron ajustable rocker arms to a set of comp cams roller rockers. about a month ago. yesterday the motor started making a lot of racket. took the valve cover off and I had broke a push rod. Upon inspection their were 3 others broke and 4 cracked. The part of the push rod braking is the cup end. The cup is breaking out. It looks like the push rod is rubbing agens the rocker itself. Do I need a special push rod to run these rockers, or are these rockers no good. Has any body had this same problem. I just rebuilt the motor about 6 months ago. It sucks to take the motor out again to chase metal around.

I would call dennis at dscmotorsport.com he sells dove (comp cams) rollers and will be able to hook you up with the correct pushrods.

Are the new rockers the stock ratio? If their not, that could be the problem. Is this a hydraulic lifter engine? If it is, maybe you got 'em too tight? Just a thought.
