I run shims under the pedestals.
1.5 mm thick.
They work fine with stock rockers.

Betreff: [Fot] Shimming the rocker pedestals ?
FoT
I just built a fresh motor with a different block and discovered my pushrods
are too long.
I had new ( big ) valves put in and started with a prepared from stock
block.
.008 was taken off the block and I canbt remember how much off the head to
give me 12.5:1 comp ratio. I would guess the head was shaved over .120b .
Anyway, while doing the final assembly and prepping to run it in, my
adjusters
are run out all the way to max. There is a full 3/16b of thread projecting
from the adjustment screw. I got cylinders 1& 2 to adjust to .22/.24 lash
but
when I got to # 3
that's where the adjuster had no effect, that was my first clue.
Our first race of the season is on the 13 th so I need to find a solution in
the next few days. One thing I have always wondered about is why couldnbt
the pedestals just be raised to compensate instead of shortening all the
pushrods.
Thanks again for input,
B
Jim G.
