What's so bad about the R16 motor? (J series content deleted!)

[Toby B <toby@wolfenet.com>]

Oh, no, Jim,
        What's wrong with the R16?  I tend to think of 'em as tough little
puppies, restrictive head design notwithstanding.  Maybe not where you'd
start for a race motor, but great for pushing a little roadster around
at reasonable speeds.
        Now, try to lash an overhead cam on it, and I'll start to agree with
you... <grin>
