<VV> Misaligned Roller Rockers

[James Cuneo]

Hello,

 Any of you run into misaligned roller rockers. I have had
this issue with two types of roller rockers. Comp Cams and Clarks.

The problem is that the roller does not line up square on the
valve stem tip. It is off to one side or the other by as much as half a valve
stem width. After 10k miles, This caused the roller to slip off to the side of
the valve tip and damage the valve. In the past I modified the push rod guide
plate by changing the location of the slot one way or another to align the
roller square to the tip. Compared to a stock rocker, the roller contact
surface is much narrower.

Am I missing something else? 

Thanks in advance,

 Jim Cuneo
