[Healeys] Vernier timing gears

[Elton Schulz]

As being a novice with respect to valve timing, what is the rationale 
for needing to adjust the valve timing and installing a Roller Master 
timing kit. What's to be gained over a stock setup?

I have previously used the Roller Master gear set with multiple key ways to adjust the cam timing with no problems on other rebuilds. What I don't like about this set is that the cap screws used to clamp the vernier gear to the hub are not very robust. Working in aviation I have AN-4 bolts that I can replace the cap screws with and safety wire them to prevent slippage.  Has anyone using this kit had problems?  I could keep the cap screws and Loctite them. This is a street car, not a race car. Pictures are one bolt installed and the hardware side by side.
