<VV> ? Rocker Failure - Twice! ??

[BBRT]

Are these stock rocker arms? Are the ones in question identical to others? 
I.e. are the holes the same in the rocker arms where oil gets squirted thru 
by pushrod tube oil? You said they all pushrods were flinging oil.. 
Including the ones in question, of course? You did use a glop of lube on 
rocker balls/arms before start-up? Check those particular arms and balls to 
make sure you didn't get an odd-ball set that isn't "New Clarks mated 
grooved ball repo
> rockers,"....mated .. Maybe you got a rocker arm that isn't true and 
> hasn't mated to ball properly.. Or?
