<VV> Roller Rocker questions

[Sethracer at aol.com]

Jim - I have some experience with both the Clarks - (Harlan Sharp/SC  
Performance) roller trunnion  rockers, and the Comp Cams rockers. First,  which 
Harlan Sharp / Clarks rockers were you running? Are they the ones  designed 
for the 140 motor? - They are different from every other Corvair  motor.   
140s take the C9401, non-140 take the C9402. Which Comp-Cam  rockers were you 
using? Which Brand/motor application? They do not make a  Corvair specific 
rocker.  Did you modify the Comp Cam rockers for use on  the Corvair?

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
