Default VW Heads -- Part 2

CC'ing Your Heads... seems to generate more messages than any of the
other head-related chores. Which is only fair since cc'ing your heads
is one of the most important tasks in building a reliable engine.
Some argue that cc'ing isn't necessary with stock heads since the spec
for stock chambers is good enough. This is called Good Enough
Engineering. The truth is, the stock spec can vary by as much as 4cc
across four chambers and that's really terrible. With nothing more
than a 50cc syringe you can adjust the chamber volume to within 1cc
across four chambers.


Couldn't you just drop BBs into the largest chambers to bring them down to
the smallest?
