I've read up a bit on those engines, and the heads have to be pulled for
valves & guides just like ours do.  I seem to recall Jake admitting as
much from time to time .. but somehow that part didn't get into this

figured out and cured, if you can get a shop to do them *right* instead
of "how the factory says to do them".
