Remember that the cam tower mounting pads probably need to be trued up
in addition to the head surface. If you don't make sure the cam tower
bores are straight the cam can in a bind. Since the cam doesn't use
bearing inserts the towers can't be aligned bored.
The L-series heads are the same design. That's why you need to select
your machine shop/machinists carefully. Many machine shops have no
idea how to do the job right.
