Milling heads.

[Philip Erickson <philip.erickson@Agouron.COM>]

Not all heads ( L-series  for one ) have removible cam towers, therefore
to correct for the top of the head being wraped you would need to
aline-bore the cam journals.
We are lucky with the design of our U20, the cam towers can be removed.
Sometime its necessary to the the cam journals aline-bored on the U20.
