|
|
Setting my rocker geometry and since it's my first time, I wanted to get a check on how they look.
1.25 rockers, CB Panchito heads (Dual hi-rev springs, titanium retainers), Web 163 cam, manton pushrods
UPDATED.....Installed lash caps and put new pics in new post below.

Do it again with lash caps, they are a must. The rocker tips will wear too fast without them. |

The scats are what I stock and use in my spring kits. |

Gene Berg lash caps. They're the only ones I've ever used that fit right. _________________ Please check my '67 sedan project progress!

I would probably cover the top of the lash cap with dykem (or a sharpie marker) and cycle through a couple of revolutions and then pull the rocker assembly off and see where it is contacting. Hard to tell from your pics, but it looks like they are running high up on the valve tip and might need the rocker stands machined down to move it down. Not uncommon on newer ratio rockers |

Thanks I'll check the swipe pattern in the next day or so. Does the arm angle look good at half lift? |

hard to see with the indacator in the way.... also be sure to check to see that the rocker foot is square to the shaft,some are not..Ive not seen any cb's that were off but I check them all.also you should be using a soft spring you can NOT get a true reading/sighting with full pressure as the rocker is pushing and pulling the valve stem this way and that. it needs to slide. they do look a little high to me..but too hard to really see. |

I see the rocker pad rolling right off the edge of the valve stem.
What kind of rockers are those?
70% of the pad will never get used. You could trim a 1/4" off the length and not miss a thing.
Lash caps are needed here.. . |

Those look like Khule Tek rockers. I have seen the same issue with pad contact with them.
I haven't found a 1.25 ratio rocker that's worth a damn. |
