[TR] cam end float

[Randall]

Did you install the cam sprocket before checking the end float?  It is what
limits how far the cam can move back, by hitting the front edge of the front
cam bearing.  The cam should not touch the plug in the back.

The lobes aren't supposed to be centered under the lifter bores.  They are
off to one side, to encourage the lifters to turn in operation, for reduced
wear.
