Blueprinting a Continental O-200

There ought to be some literature on this subject since so many O-200's have
been installed on the noses of Formula 1 racers and revved up to 4.5k rpm
while rocketing around the pylons.

Hows about it? Anybody know where it can be found? A fellow named
Fehling wrote essays on how to improve the performance of the O-200. Does
anyone here know where this material may be found?

And, yes, I'm looking for an O-200 to buy, preferably a low-time core.
